Abstract

Uncoded and coded optical pulse position modulation (PPM) systems are compared for both direct and heterodyne detection. Simulations of these systems with different code rates are included, and the gains obtained in the coded cases are reported. By using Reed-Solomon codes, it is seen that the performance of a coded system is improved over an uncoded system in direct detection. As the code rate is reduced, the system performance gets better. Among the three different code rates tested, the code rate of 1/3 seems to be the best choice. The same applies to the heterodyne detection system. When Reed-Solomon codes are applied to a heterodyne system, it is observed that the efficiency of the system improves.<>
