Performance of ultra-wideband time-shift-modulated signals in the indoor wireless impulse radio channel

Impulse radio (IR) is a spread spectrum (SS) wireless technique in which ultra-wideband (UWB) communication waveforms that consist of trains of time-shifted sub-nanosecond pulses are modulated to convey information exclusively in the relative time position of the pulses. We make an assessment of the performance of non-binary IR modulation in the presence of multipath with detection using a RAKE receiver.
