Summary:
Study of waveform distortion is necessary for designing optimum ultra wideband impulse radio (UWB-IR) systems because the distortion of waveform degrades the performance of correlation receiver. In this paper, the novel quantitative parameter of waveform distortion that is peak to average loss ratio is proposed and derived in the closed form formula for UWB-IR transmissions. The peak to average loss ratio is defined as the ratio between peak power loss and average power loss from transmitter (Tx) to receiver (Rx). The free space and ground reflection channels are considered. The results obtained from proposed formula are compared with measurement. This proposed parameter is useful to define the quantity of waveform distortion in UWB-IR systems.
