Abstract :
A receiver for optical Deep Space Communication System (DSCS) is designed and modeled. A detailed architecture of the Pulse Position Modulation (PPM) and demodulation is addressed and simulated. The optical link part and the free space channel are also designed and simulated. Physical characteristics of the free space communication channels are modeled, including path attenuation, noise, distortions, time delay, etc. Preliminary results show that external modulation is adequate for characterizing complex and costly DSCS links.
