Summary

NASA is developing technology for 64 64-ary PPM using relatively large PPM time slots (10 ns) an and relatively simple d electronic electronic-based receiver logic. In this paper we describe photonic photonics-based receiver options for the case of much higher data rates and inherently shorter decision times. The receivers take the form of virtual ( array or quadrant) arrays with associated comparison tests. Previously we explored this concept for 4-ary and 16-ary PPM at data rates of up to 10 Gb/s. The lessons learned are applied to the case of 64 64-ary PPM at 1.25 Gb/s s. Various receiver designs are compare, and t the optimum design, based on virtual array he arrays, is s, evaluated using numerical simulations.
