AbstractPulse position modulation (PPM) has many attractions for optical communication over deep space and for intersatellite communications. This paper describes a variate of PPM, known as differential pulse position modulation (DPPM) which can double the data throughput relative to PPM. We begin this paper with a survey of various laser sources and laser modulation techniques used in modem space optical communications. We then discuss the advantages of the combination of DPPM and Reed-Solomon (RS) codes.
