MAP Detectors for Differential Pulse-Position Modulation over Indoor Optical Wireless Communications

摘要

In this letter, it is shown that a MAP detector can be employed with differential pulse-position modulation (L-DPPM) in an indoor optical wireless system. The MAP detector error performance is evaluated and compared with that of a hard-decision detector and MLSD over an in-tersymbol interference channel. It is shown that a MAP detector provides superb performance even in a dispersive channel with high D_T.
