On the performance of dual‐branch selection diversity combining in α−κ−μ fading environments

Abstract

In this paper, the performance of a dual-branch selection combining (SC) system is analyzed over − − fading channels. First, an outage probability (OP) expression is presented for a dual-branch diversity with the SC scheme in − − fading channels by using cumulative distribution function (CDF). By using the probability density function (PDF) and CDF of − − distribution, the PDF of total output instantaneous signal-to-noise ratio (SNR) is obtained which is subsequently utilized for the analysis of the considered system. Based on this PDF expression, bit error probability (BEP) expressions are derived with the use of a simple and tight upper bound approximation of Gaussian Q-function. In addition to these, we propose analytical effective capacity (EC) expressions for a dual-branch SC system under − − fading conditions. Then, we present simplified expressions for the OP, BEP, and EC at high SNR. Finally, we illustrate the OP, BEP (for binary phase shift keying and quadrature phase shift keying modulation formats), and EC performances for different configurations of , , and parameters. In order to validate our analytical results, comparisons between the exact simulations and analytical results are also provided.Trans Emerging Tel Tech. 2019;30:e3719.wileyonlinelibrary.com/journal/ett

A Generalized Approach on Outage Performance Analysis of Dual-Hop Decode and Forward Relaying for 5G and beyond Scenarios

“…To date, a number of studies have been performed on the performance analysis of relay-aided wireless communication systems [12,[17][18][19][20][21][22][23]. The authors in [17] derived the expression of the outage probability for a dual-hop DF relaying over a Rayleigh-generalized gamma fading channel.…”

“…The performance of a single-branch single-relay AF relaying system over mixed Rayleigh-Nakagami-m fading was analyzed by Benmahmoud in [21]. Kapucu in [22] analyzed the performance of a dual-branch selection combining scheme over α − κ − µ fading. The bit error rate (BER) expression for an M-ary phase-shift keying industrial cooperative relaying system was derived over generalized-K composite fading channels by Marjanovic et al [23].…”

In, 17 the OP, ABER, and ACC for a two-branch SC receiver for 𝛼-𝜅-𝜇 faded channels are studied, however, the derived ABER expression is not exact and generalized ABER and also the derived EC expression is not valid for non-integer 𝜇. In, 18 authors have studied capacity L p -norm diversity combining receivers in generalized fading channels.…”
