A novel closed-form of ASEP and channel capacity with MRC over η − μ/IG distribution

In this work, we analyse and investigate the performance of wireless communication systems with maximal ratio combining (MRC) over η − μ/Inverse Gaussian (IG) composite fading channel. All formats of coherent schemes are considered and novel closed-form expressions of average symbol error probability (ASEP) with diversity are derived. Also, the novel closed-form expressions of channel capacity under transmission schemes such as optimal rate adaptation (ORA) and channel inversion fixed rate (CIFR) are derived and analysed with MRC diversity over η−μ/IG composite fading distribution. The closedform results have been validated with the Monte Carlo simulation as well as the exact results.
