Performance analysis of Hoyt-lognormal composite fading channel

Hoyt distribution is used to model the wireless communication system with more severe channel fading conditions. The large-scale signal power variation is statistically modeled by the lognormal distribution. Due to mathematical complexity, performance parameters of Hoyt-lognormal composite fading channels are not present in closed-form. In this paper, we have analyzed the performance of Hoyt-lognormal channel by using the Gaussian-Hermite quadrature sum method. The performance analysis of probability density function (PDF) of the signal to noise ratio (SNR), outage probability (Pout), amount of fading (AF), average symbol error probability (ASEP) are analyzed and expressed in closed form. With high accuracy, the proposed closed form approximation of composite fading channel is compared with the exact results.
