Real-time correlation of 31 chip binary p.s.k. waveforms has been obtained using nonlinear interactions of acoustic surface waves, with a signal bandwidth of 8 MHz. A dynamic range of 20 dB was obtained. Calculations indicate that a dynamic range of 50 dB should be obtainable quite readily, making the device attractive for adaptive signal processing.
