Paper Abstract

Dual Head Pulse Interval Modulation (DH-PIM) is a modulation technique using in optical wireless communications. In this paper, the performance of DH-PIM is analyzed in the presence of intersymbol interference. The channel impulse response and symbol error rate versus normalized delay spread are discussed. A soft-decision decoding technology is presented, which can improve the performance of DH-PIM.
