Performance of Overlapped and Orthogonal TH-BPPM UWB Systems

This paper describes a modulation scheme for TH- UWB systems using pulse position modulated (PPM). For this scheme, a set of overlapped and orthogonal signals are transmitted simultaneously in the same time slot resulting in a composite pulse. And the signals have been discussed analytically for AWGN and multi-path channels. The proposed scheme can achieve an excellent BER performance by using one signaling over another.
