Coherent Optical Receiver for PPM Signals under Atmospheric Turbulence
Adaptive combining of experimentally obtained heterodyned pulse position modulated (PPM) signals with pulse-to-pulse coherence in the presence of simulated spatial distortions resembling atmospheric turbulence is demonstrated. The adaptively combined PPM signals are phased up via an LMS algorithm suitably optimized to operate with PPM in the presence of additive shot-noise. A convergence analysis of the algorithm is presented, and results with both, computer simulated and experimentally obtained PPM signals are analyzed.
Performance analysis and preliminary experimental verification of a coherent optical receiver for PPM signals in the presence of atmospheric turbulence
We present the performance analysis and experimental verification of a coherent free-space optical communications system in the presence of simulated atmospheric turbulence.
