Proposal of a time-hopping pulse spacing modulation system with restricted amplitude levels

Abstract

In this paper, a time-hopping pulse spacing modulation system with restricted amplitude levels is proposed. The proposed system uses several PN codes, and it transmits the information by the interval between the successive PN codes. The bit error rate performance and the synchronization performance of the proposed system on the additive white Gaussian noise (AWGN) channel are evaluated by theoretical analysis. As a result, there is the optimum preamble pattern for bringing the probability of block error that takes into account the synchronization performance close to the lower bound.
