Abstract

This paper introduces a new modulation scheme, dual-amplitude pulse interval modulation (DAPIM) for optical wireless communications. We present the expression for bandwidth requirement, slot and packet error rates, and optical power requirements in a nondispersive channel. We find that DAPIM achieves improved bandwidth and/or power efficiency compared with OOK, PPM, and PIM. DAPIM with 4 bits and 5 bits per symbol is attractive in terms of optical power and bandwidth requirements.
