Abstract
Non-Coherent Autocorrelation (AR) UWB receivers are preferred over coherent UWB receivers because it requires no channel state information (CSI) and hence is less complex in nature. The paper investigates the performance of Transmitted Reference (TR) and Differential Transmitted Reference (DTR) scheme using AR UWB receivers. Theoretical analysis of BER performance of non-coherent IR-UWB receivers is also discussed at large and compared with simulation results. Analytical and simulation results reveal that non-coherent IR-UWB DTR receiver outperforms TR receiver by a margin of 3-4 dB in AWGN and IEEE 802.15.4a UWB environment.
