Performance Analysis of mmWave Communications With Selection Combining Over Fluctuating-Two Ray Fading Model

In this letter, the performance of millimeter-wave (mmWave) communications with selection combining (SC) over non-identical fluctuating two-ray (FTR) fading channels is analyzed. Consequently, the exact expressions and asymptotic approximations at high signal-to-noise ratio (SNR) regime of the moment generating function (MGF) and probability density function (PDF) of the maximum of non-identical FTR variates are provided. To this effect, mathematically tractable expressions of the outage probability (OP), outage capacity (OC), average bit error probability (ABEP), and average channel capacity (ACC) are derived. The truncation of the infinite series of the cumulative distribution function (CDF) for a specific number of terms is also given. A comparison between the numerical and simulated results is performed to verify the validation of our analysis.
