Abstract


Spectral amplitude coding (SAC)-optical code division multiple access (OCDMA) being an ensuring advancement gives satisfactory response for burst and asynchronous environment. While free space optics (FSO) transfer information from one place to another at high speed where other systems are hard to reach. This paper offers and endeavors to dissect the performance of the system (SAC-OCDMA) through diverse environment conditions in FSO channel utilizing Zero cross correlation code having bit rate of 70 (10×7) Gb/s for seven users. In doing so, the influence of distance on the performance of SAC-OCDMA has been compared. The simulative investigation has been carried out as far as significant parameters like bit error rate (BER) and Eye diagrams. It has been observed from the comprehensive simulations that the system performance improves with an optical amplifier by 30.7%, 32.4%, 15% and 20.9% in clear weather, heavy haze, moderate Fog and heavy rain respectively.

Keywords: FSO, SAC-OCDMA, ZCC code, Multi Access Interference (MAI), bit error rate (BER)
