研究目的

To model the communication channel under weak, moderate, and strong turbulence conditions using Double Generalized Gamma (GG) distribution and to improve the performance of Free Space Optical (FSO) Communication system by analyzing the Bit Error Rate (BER) performance of Hybrid Subcarrier Intensity Modulation (SIM) with L-Pulse Position Modulation (L-PPM) and Minimum Shift Keying (MSK).

研究成果

The Hybrid SIM with L-PPM and MSK modulation technique over Double GG distribution in FSO Communication system performs better in turbulence induced fading for weak, moderate, and strong turbulence conditions. BER decreases with a decrease in the average length of PPM symbol L.

研究不足

The study is limited to simulation results and does not include practical implementation challenges. The range of average received irradiance is between -12 dBm and 4 dBm, and the analysis is based on specific parameters under weak, moderate, and strong turbulence conditions.
