A top-loaded, inductively-coupled, electrically small antenna is designed for HF ground wave transmission. A genetic algorithm is used to optimise the antenna parameters. Two prototype antennas have been built and the test results match well with simulations. Both antennas have an electrical size kr of 0.2, greater than 65% efficiency and transmission performance within 1 dB of a commercial whip. - Author(s): S.-S. Oh ; J. Heo ; D.-H. Kim ; J.-W.

A low-cost broadband millimetre-wave planar 30×30 array antenna is presented. The antenna is fed by a microstrip feed network in the H-plane to decrease fabrication costs, and a waveguide feed network in the E-plane to reduce the feed line loss. The waveguide and microstrip feed network are coupled through the proposed slot pair. The slots are placed one quarter of a guided-wavelength distance apart, so that the reflected waves from the slots cancel each other. A conductive bar is laid above the slots to increase the coupling, which increases the antenna gain by about 1 dBi. The maximum gain is 30.5 dBi at 41.5 GHz. The measured bandwidth is as broad as 7.1%. - Author(s): B. Sanz-Izquierdo ; J. Batchelor ; R. Langley

A prototype of a ‘real-time’ 64-channel spherical measurement system for determining the complex radiated far fields of active mobile terminals is presented. The system does not require any RF feed cables to be connected to the mobile terminal. Test measurements show that the complex far field can be determined with an acceptable accuracy. The system thus provides, together with the radio-channel data, a basis for realistic and fast estimation of MIMO performance of a mobile terminal. - Author(s): C. Migliaccio ; J.Y. Dauvignac ; L.

A W-band high gain lens antenna has been realised and measured. A hyperbolic lens made in ECCOSTOCK 0005 is associated to an optimised modified circular horn related to a circular-to-rectangular waveguide transition in order to fit the WR-10 standard waveguide. The antenna provides more than 30 dBi gain between 75 and 110 GHz. It is competitive in several fields of applications: first, obstacle detection radar application (at 77 or 94 GHz), secondly metrology, for example, in order to measure radar cross-sections over the whole W-band with a single antenna.

Verification was sought for the memory operation of a single transistor type ferroelectric random access memory (1T type FeRAM) with a circuit model for a memory cell transistor combined with a precharged capacitive decoupling sensing scheme. The wiring scheme of the 1T type FeRAM array was also proposed based on the operation of the fabricated memory cell transistor. As a result, the memory operation of 1T type FeRAM was confirmed at a low current level with high sensing speed and no reference cell, and the design and verification of the full chip were achieved.

A radiated susceptibility test is presented that exploits crosstalk to inject electromagnetic energy into the termination networks of the system under test. Crosstalk is generated via an additional circuit loop, mounted in close proximity of the system harness. Equivalence with worst-case interference due to an external plane wave is achieved by feeding the additional circuit via a sinusoidal source with frequency piecewise-linear amplitude.

A CMOS pixel with local processing suitable for use in a modulated light camera is described. The pixel was designed to detect sinusoidally modulated light within the frequency range of 500 kHz–25 MHz. It consists of a photodiode, a transimpedance amplifier, a mixer and an active 150 Hz bandpass filter. It is a prototype design capable of further size reduction suitable for tiling into an array for imaging purposes. This allows the modulated light component of a frequency far in excess of the frame rate to be detected at the pixel level. - Author(s): M.C. Pitter ; R.A. Light ; M.G. Somekh ; M. Clark ; B.R.

The total path attenuation at 11.6 GHz measured at Suva, Fiji (Lat.: 18.08°S, Long.: 178.3°E) for one year (April 02–March 03) is presented. It shows logarithmic function with ground rain-rate and saturates at very high rain-rate. A rain-rate of 40 mm/h at this station causes the Ku-band attenuation threshold (>7 dB) to be exceeded. Maximum exceedences for both attenuation and rain-rate at the station were observed during the wet months (November–April). - Author(s): C. Liu and F. Li

The orthogonal frequency-division multiplexing (OFDM) modulation format has been adopted in the USA, Europe, and Japan as the standard for wireless local area networks (WLAN), digital broadcasting, and future fourth generation mobile communication (4G). In-band and out-band spectral control requirements in terms of the power spectral density (PSD) of OFDM signals are set in these standards. Presented is the derivation of the PSD of OFDM signals using an IEEE 802.11a example. The accurate analytic expression of the PSD of OFDM signals is very helpful for further OFDM system design in terms of in-band and out-band spectrum regrowth analysis.

The compensation of intra-channel nonlinear effects in a CSRZ 40 Gbit/s 32×100 km system using an LiNbO3 optical phase conjugator in a re-entrant, recirculating loop architecture, is experimentally demonstrated. Two decades of improvement in the bit error rate at 3200 km with phase conjugation has been achieved. Also, the performance of CSRZ and RZ-DPSK modulation formats at 3200 km with and without optical phase conjugation is compared. - Author(s): T. Tokle ; Q.N.T. Le ; C. Peucheret ; P. Jeppesen

A new technique for mitigating Doppler aliasing artifacts in synthetic aperture radar (SAR) imagery is demonstrated. The technique uses continuous-wave (CW) transmission of randomised stepped-frequency waveforms. Subsequent processing places Doppler aliasing artifacts in Doppler filter nulls, effectively removing them from the imagery. Simulated 2-D SAR images illustrate the effectiveness of the technique. - Author(s): E. De Witte and H.D. Griffiths

A continuous nonlinear FM waveform design capable of achieving range sidelobe levels of better than −70 dB, suitable for use with a satellite-borne precipitation radar, is presented. The waveform shows good Doppler tolerance. It is shown that slowly-varying phase and amplitude errors in the transmitter and receiver have relatively little effect, but rapidly-varying errors result in paired echo sidelobes, the level of which can be significant. A closed-loop calibration system will undoubtedly be required to remove such errors.

A block affine projection algorithm that is less complex but mathematically equivalent to a recently proposed Gauss-Seidel pseudo affine projection (GS-PAP) algorithm is proposed. This reduced complexity is achieved by applying a partitioning method to the original sample-by-sample algorithm. It is shown that the derived algorithm has better convergence and tracking abilities than those of the NLMS algorithm. Its application in an acoustic echo cancellation is investigated. - Author(s): T. Yang and W.B. Mikhael

An efficient digital image suppression technique for binary phase shift keying receivers based on independent component analysis is presented. It requires only one antenna and single downconversion path. As a result, the receiver's complexity is much lower than that of quadrature or dual-antenna receivers. Simulation results confirm that the performance of the simplified receiver is comparable to other more complex receivers. - Author(s): H.-I. Kim and S.-K. Park

A voice activity detection (VAD) algorithm using the radial basis function (RBF) network is proposed. The k-means clustering and least mean square algorithms are used to update the RBF network to the underlying speech condition. The inputs for RBF are code excited linear prediction coder parameters, which are stable under background noise. The RBF network output is compared to a threshold to determine the nature of the period (voice or silence). Experimental results show that the proposed VAD algorithm achieves better performance than G.729 Annex B at any noise level.
