Spectral Amplitude Coding Optical CDMA: Performance Analysis on Free Space Optical Channel
International Journal of Engineering & Technology
In this paper, we investigate the performance of Spectral Amplitude Coding Optical Code Division Multiple Access technique based on Free Space Optical channel. SAC OCDMA is one of the most popular multiplexing techniques since many years and FSO is gaining popularity and is very useful especially in point to point communication. The system presented in this paper utilizes Walsh Hadamard code as signature code. The coder and decoder structures are based on optical filters of fiber Bragg gratingsdoi:10.14419/ijet.v7i4.38.24314 fatcat:5fxixat7snawfevzqy4vadjcce
