In this paper, the outage probability performance of the parallel relay-assisted FSO communication system is analyzed. Firstly, a new aggregated channel fading model is established, which includes atmospheric attenuation, M-distributed atmospheric turbulence and nonzero boresight pointing error. After that, the statistical characteristics of the aggregated channel are analyzed. Under the aggregated...
Free-space optical (FSO) communications has recently received significant attention and commercial interest for a variety of applications. In this paper, the outage probabilities for both the parallel and serial relay-aided FSO communications are analyzed. Initially, a new aggregated channel fading model is established, which considers atmospheric attenuation, ${\cal M}$-distributed atmospheric turbulence,...
This paper studies the system uplink outage probability in distributed antenna systems (DAS). Firstly, owing to the complexity of actual wireless environments, this paper establishes a composite channel model which takes path loss, lognormal shadowing and Rayleigh fading into account. Then, the probability density function (PDF) of the output signal-to-noise ratio (SNR) is derived. After that, an...
