Performance evaluation of finite-resolution IR-UWB signal detection

Finite-resolution digital receiver is considered to be a potential solution to meet the severe demand of ADC that results from wideband of IR-UWB signal. However, the quantized distortion is totally different from full-resolution quantized signal. In this paper, the finite-resolution quantized signal model is derived. Based on the correlation receiver, estimation and detection performance of finite-resolution and full-resolution digital receiver are analyzed in the paper. The analytical results agree with the numerical results exactly and the template estimation performance using midtread quantizer is better than that using the adjacent midrise quantizer. © 2013 Trans Tech Publications Ltd, Switzerland.
