Optimization of UWB non-coherent receiver

The optimization on BER performance of UWB non-coherent receiver based on OOK scheme is investigated. The optimum parameters combination of length of integration interval and SNR in the integration interval, which makes the BER minimum, is obtained theoretically and practically. A modified least-squares-based algorithm is proposed in this study, which applies the Gaussian approximation to the exact optimal threshold. Meanwhile, the feasibility of the traditional approximation is explored. The results show that, compared with the conventional method, the optimum parameters proposed in the study increase the system performance greatly.
