Abstract

In this paper, we propose a multiple-pulse interference (MPI) cancellation scheme for ultra-wideband systems using pulse shape modulation. The proposed scheme is based on a similar concept to parallel interference cancellation for code-division multipleaccess systems, where a specific training sequence structure is used to estimate the channel information and interference for MPI cancellation. Computer simulation results are given to show that it has much better performance than the maximum ratio combining scheme in different scenarios.
