Abstract :
The performance of several ultra-wideband (UWB) transmission schemes is analysed when the channel is frequency selective so that inter-symbol-interference (ISI) arises at the receiver. The UWB schemes considered employ time hopping (TH) and/or direct sequence (DS) as spreading method and a correlation receiver. Analytical expressions for the signal to interference power ratio (SIR) are derived are used to compare the schemes over several channels. Also the bit error rate (BER) is discussed. The theoretical results are compared with simulation results
