Abstract

Non-coherent receivers such as transmitted reference receivers attracted much interest, recently, due to the complexity of coherent UWB receivers. In this paper, we investigate the impact of channel state information (CSI) on Ultra Wideband (UWB) transmitted reference (TR) maximum likelihood (ML) receivers in the presence of a UWB co-channel interferer (CCI). TR ML receivers are derived assuming following kinds of channel state information: full CSI, knowledge of the magnitude of the channel impulse response, and no CSI. We compare the performance of these ML estimators with and without CCI by means of bit error ratio simulations.
