Abstract

Spatial diversity technique is one of the mitigation techniques to combat the effect of atmospheric turbulence. In this paper, a spatial diversity technique with equal gain combining (EGC) is employed to analyze the performance of ground to deep space optical link receiver for various modulation schemes viz., OOK, Subcarrier Intensity Modulation (SIM) and M-ary PPM. It is observed that BPPM continue to perform better than the M-ary PPM (M=8, 16, 64 and 256) even with the spatial diversity. SIM outperforms the other schemes in terms of lesser SNR requirement for a given BER.
