An innovative multiuser communication system based on the ultra-waveband (UWB) technique is studied. Two coding techniques are proposed: the first is based on direct-sequence code-division multiple access (DS-CDMA) associated with the UWB system. The second innovative technique uses orthogonal functions called modified Gegenbauer functions. To evaluate the performances of these techniques, bit error rate values are calculated and analysed using computer simulations. It is shown that Gegenbauer functions offer superior performance to the previously proposed DS/CDMA-UWB technique for multiuser communications system.
