Summary: 
The capacity of Multi-pulse PPM (MPPM) and performance of Reed-Solomon coded MPPM in optical photon communications are evaluated. Transmission rate, energy efficiency and error probability of MPPM are presented for noiseless channel. It is shown that MPPM yields higher limits of energy efficiencies as well as transmission rate than PPM in band limited channel. Moreover, it is shown that MPPM combined with Reed-Solomon (RS) codes achieves higher energy efficiency of more than twice as that of RS coded PPM, which McEliece studied, in practical range of error probability.
