Selection Combining Scheme Over Non-Identically Distributed Fisher-Snedecor F Fading Channels

Abstract

In this paper, the performance of the selection combining (SC) scheme over independent and non-identically distributed (i.n.i.d.) Fisher-Snedecor F fading channels is analysed. Accordingly, the probability density function (PDF) and the moment generating function (MGF) of the maximum of i.n.i.d. Fisher-Snedecor F variates are derived first. Based on these statistics, the exact expression and the asymptotic behaviour at high average signal-to-noise ratio value of the average bit error probability (ABEP), the normalised average channel capacity (ACC), and the average area under the receiver operating characteristics curve (AUC) of the energy detection based spectrum sensing with i.n.i.d. SC diversity receivers are provided. To validate our analysis, the numerical results are compared with the Monte Carlo simulations.

On the Performance Analysis of Switched Diversity Combining Receivers over Fisher–Snedecor ℱ Composite Fading Channels

“…Compared to the well-known generalized K composite fading model, this model not only provides more tractable and simpler mathematical formulations of the statistical characteristics but also shows a better fit to experimental channel measurements in some emerging wireless communications applications, for example device-to-device communications and wireless body area networks. As a result, a good deal of research work has been done based on the Fisher–Snedecor composite fading channel model, such as [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ] and references therein. By applying the diversity combining schemes, the authors in [ 34 ] analyzed the performance of the MRC system over independent and non-identically distributed (i.n.i.d.)…”

“…The performance of the PSC scheme with i.n.i.d. branches was analyzed in [ 36 ]. The authors in [ 37 ] analyzed the channel capacity under different power adaption schemes for MRC diversity system over independent and identically distributed (i.i.d.)…”

“…Although the performance of MRC and PSC systems has been investigated over independent [ 34 , 35 , 36 , 37 ] and correlated [ 38 ] fading channels, to the best of the authors’ knowledge, the performance of the SDC systems over independent and correlated Fisher–Snedecor fading scenarios has yet to be considered in the open research literature. Motivated by the above observation, we will try to fill this gap and provide a comprehensive systematic investigation and certain significant insights about SSC, SEC, and SECps schemes in terms of their potential applications (such as device-to-device, wearable, and Internet of Things applications) over Fisher–Snedecor fading channels.…”

“…Bugüne kadar Fisher-Snedecor F sönümlü kanallarda çeşitli haberleşme sistemlerinin performansları analiz edilmiştir ve bazıları [11][12][13][14][15][16][17][18][19][20][21][22]'de verilmiştir. [11]'de tek girişli tek çıkışlı bir sistemde sayısal modülasyonların Fisher-Snedecor F sönümlü kanallardaki performansı sunulmuştur.…”

“…[15] Fisher-Snedecor F değişkenlerin çarpımı ve oransal çarpımını ele alarak kaskat F kanalında performans analizi ile spektrum paylaşımlı ağların performans analizini ortaya koymuştur. [16]'da F sönümlü kanallarda SC alıcıların, [17][18][19]'da ise MRC alıcıların performansı sunulmuştur. [20]'de ise F sönümlü kanalların seviye geçiş oranı (level crossing rate) ve ortalama sönüm süresi (average fade duration) bulunmuştur.…”
