Two new energy detection (ED) Ultra-Wideband (UWB) systems are proposed in this dissertation. The first one is an ED UWB system based on pulse width modulation (PWM). The bit error rate (BER) performance of this ED PWM system is slightly worse than ED pulse position modulation (PPM) system in additive white Gaussian noise (AWGN) channels. However, the BER performance of this ED PWM system surpasses that of a PPM system in multipath channels since a PWM system does not suffer cross-modulation… 
Transmission rate and bit error rate (BER) performance are two important parameters for ultra-wideband (UWB) communication system. Among the widely used modulation schemes, pulse position modulation

A Survey on Various Coherent and Non-coherent IR-UWB Receivers
An in depth study on the receivers concludes that, non-coherent IR-UWB receiver is preferred over its counterpart coherent IR- UWB receiver even though it comes at the expense of poor BER performance, and simulation results prove that, though the performances are same, the low complexity of energy detector receivers gives an edge over the autocorrelation receivers.
