However, the existing model does not consider pointing error impairment. To fill this gap, in this letter, we derive novel closed-form expressions for the probability density function (PDF) and cumulative distribution function (CDF) for irradiance fluctuations in the presence of pointing error impairments. Subsequently, the PDF and CDF of the received signal-to-noise ratio (SNR) are derived and employed to obtain novel closed-form expressions for the outage probability, average bit error rate, and average ergodic capacity. To gain more insight into the impact of system and turbulence channel parameters, simple and accurate asymptotic expressions are further derived. Our analytical results are supported by Monte-Carlo simulations to validate the analysis. {\textcopyright} 1997-2012 IEEE.}, keywords = {Asymptotic expressions, Average bit-error rates, Average ergodic capacities, Bit error rate, Closed-form expression, Cumulative distribution function, Distribution functions, Errors, Free Space Optical communication, Monte Carlo methods, Optical communication, Performance analysis, Probability density function, Probability density function (PDF), Signal to noise ratio, Turbulence}, doi = {10.1109/LCOMM.2020.3042489}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85097943147\&doi=10.1109\%2fLCOMM.2020.3042489\&partnerID=40\&md5=d5175f79c64955ba088a76dbd3e88c91}, author = {Badarneh, O.S. and Derbas, R. and Almehmadi, F.S. and El Bouanani, F. and Muhaidat, S.} } @article {12053057320170104, title = {A tight approximate analytical framework for performance analysis of equal gain combining receiver over independent Weibull fading channels.}, journal = {EURASIP Journal on Wireless Communications \& Networking}, volume = {2017}, number = {1}, year = {2017}, pages = {1 - 12}, abstract = {In this paper, a method for approximating the probability distribution of sum of independent and identical Weibull random variables is adopted to analyze the performance of equal gain combiner (EGC) receiver over non-identical Weibull fading channel (WFC). Our main result is to derive a generalized expression of the probability density function (PDF) of the signal-to-noise ratio (SNR) at the EGC output in the case of non-identical WFC. Based on this PDF, accurate approximation of significant performance criteria, such as outage probability (OP), the amount of fading (AoF), and average symbol/bit error probability (ASEP/ABEP), are derived. In addition, we derived the analytical expressions for channel capacities under various adaptation policies such as optimal rate adaptation (ORA), optimal simultaneous power and rate adaptation (OPRA), channel inversion with fixed rate (CIFR), and truncated channel inversion with fixed rate (TCIFR).
