Abstract

Adequate data rate is always desired in wireless communication channels. Previously, few fading models were used to model wireless communication channels and to perform analysis on them. In this paper, analyses of data rate limit of single-input single-output (SISO) wireless communication system over Nakagami-q fading channels are presented. The calculation of capacity has been carried out using small and large limit argument approximations. The analytical solution for channel capacity is presented using small and large limit argument approximations. Where small and large limit argument approx-imations correspond low and high signal-to-noise ratio (SNR) regime. Behavior of channel capacity with respect to SNR and fading parameter respectively has been investigated deeply. The comparison of the channel capacity behavior for both low SNR and high SNR regime and have also been done and analyzed. It has found that the channel capacity increased with increasing SNR in low SNR regime. The channel capacity also behave in the same manner in high SNR regime as well.

Summary

INTRODUCTION

Having a good data transfer rate in wireless communication system is always expected for users. In [4], authors presented results based on their findings on the capacity of discrete-time Rayleigh-fading SISO and MIMO channels. Nakagami-m, Rician and Rayleigh distributions are popular distribution models for research on SISO, SIMO, MIMO channels. Besides these distribution there is Nakagami-q distribution known as Hoyt distribution which is a type of fading distribution that under indisputable conditions serves a decent model. Study of the data rate limit of SISO wireless communication system over this Nakagami-q fading channels is done. The calculation of the capacity for low and high SNR regimes based on Nakagami-q distributions including the comparison of them have been done in order to analyze how consistent and good the data rate limits are with respect to instantaneous SNR and fading parameter.
