Outage Probability Analysis of Free Space Communication System Using Diversity Combining Techniques
Source abstract
Abstract
Recently, free space optical (FSO) communication is gaining much attention towards the research community. The reason for this attention is the promises of high data-rate, license-free deployment, and non-interfering links. It can, however, give rise to major system difficulties concerning alignment and atmospheric turbulence. FSO is the degradation in the signal quality because of atmospheric channel impairments and conditions. The worst effect is due to fog particles. Though, Radio Frequency (RF) links are able to transmit the data in foggy conditions but not in rain. To overcome these issues related to both the FSO and RF links. A free space communication system (FSCS) is proposed, in which the hybrid technology is based on the individual FSO and RF channel. FSCS is a capable solution to overcome the difficulties of the existing systems (FSO and RF) as well as to enhance the overall link reliability and availability. In this paper, FSCS is investigated in terms of performance throughput (i.e., outage probability and bit-error-rate (BER)) by implementing the receive diversity combining techniques. An analysis of the outage probability of the proposed system along with the individual FSO and RF system is developed. Simulation results are presented to support the analysis. It is shown that the proposed system outperforms the individual FSO and RF system and gives a power gain of 3dB over a distinct number of receive antennas.
