Performance Analysis of Rectangular QAM With SC Receiver Over Nakagami- $m$ Fading Channels
Dharmendra Dixit,P. R. Sahu +1 more
TL;DR: A novel exact closed-form expression for average symbol error rate (ASER) for general order rectangular quadrature amplitude modulation (RQAM) scheme is derived using cumulative distribution function based approach.
Journal ArticleDOI
Performance of L-Branch MRC Receiver in η-μ and κ-μ Fading Channels for QAM Signals
Dharmendra Dixit,P. R. Sahu +1 more
TL;DR: A simple and highly accurate approximation to the average symbol error rate (ASER) expression of quadrature amplitude modulation (QAM) scheme is derived and is compared with Monte Carlo simulation to verify the accuracy of the derivation.
Journal ArticleDOI
Performance analysis of QAM in amplify-and-forward cooperative communication networks over Rayleigh fading channels
TL;DR: In this article, the performance analysis of quadrature amplitude modulation (QAM) schemes for cooperative amplify-and-forward (AF) dual-hop relaying system over independent and identically distributed (i.i.d.) Rayleigh fading channels is presented.
