Ultra-wideband (UWB) is a useful radio technique for sharing frequency bands between radio systems. It uses very short pulses to spread spectrum. However, there is a potential for interference between systems using the same frequency bands at close r

An OFDM transmission is robust to the multipath delay due to the addition of a cyclic prefix (CP). However, it will suffer from an inter-block-interference (IBI) under a severe long delay multipath channel whose channel impulse response (CIR) is long
