摘要：
A novel High Data Rate (HDR) Prerake DS UWB multiple access system is proposed, in which the number of taps in the Prerake filter is set to a large value while keeping the number of taps in a chip sufficiently small. Hence high data rate is achieved without sacrificing signal energy captured. We derive the higher order moments of Multiple Access Interference (MAI) and fit the distribution of MAI using a generalized Gaussian distribution. Numerical results are provided to show that generalized Gaussian distribution is a more appropriate model for the distribution of MAI. Next, accurate BER formula is derived using the Characteristic Function (CF) method. Numerical results show that the HDR Prerake DS UWB system outperforms the conventional Partial-Prerake DS UWB system.
