摘要

In this paper, an MPPM-PSM scheme, that is a fusion of the Multi-pulse Pulse Position Modulation(MPPM) scheme and the Pulse Spacing Modulation (PSM) scheme, is investigated in optical wireless communications. In particular, the block error rate is derived in the presence of scintillation, background light, shot noise and thermal noise. As a result, the data transmission rate of the MPPM-PSM scheme is better than those of the conventional MPPM scheme and the conventional PSM scheme. Moreover, in the MPPM-PSM scheme, when the number of information bits per block is fixed, block error rate is improved by reducing the number of frames per block.
