Performance Analysis of OSTBC for Partial Relay Selection with Correlated Antennas over Nakagami-m Fading

Abstract

This letter considers the performance for partial relay selection of a dual-hop relay system with correlated antennas at each node. Orthogonal space time block coding (OSTBC) is employed at the source and the best relay. The source communicates with the destination through a relay with the maximum signal-to-noise-ratio (SNR) in the first hop. We assume non-identically distributed Nakagami-m fading channels. The closed form expressions of outage probability, the symbol error rate (SER), and the generalized higher moments of instantaneous end-to-end signal-to-noise-ratio (SNR) are provided. A tight approximation of ergodic capacity is evaluated and an asymptotic approximation is provided to obtain the diversity order. Analytical results are validated with Monte-Carlo simulations using Mathematica and MATLAB programs.

Performance Analysis of AF Relaying With Selection Combining in Nakagami-$m$ Fading

“…Incremental DF and AF relaying were considered in [7] for analyzing the diversity multiplexing tradeoff. Orthogonal space time block coding was assumed in [8] for deriving closed formula of higher moments of end-to-end signal to noise ratio (SNR).…”

On the Performance of Cognitive Underlay SIMO Networks over Equally Correlated Rayleigh Fading Channels

“…On the other hand, multiple-input multiple-output (MIMO) is an advanced technology that can effectively exploit spatial multiplexing and antenna diversity gains as compared with traditional single-input single output (SISO) systems [9,10]. However, the performance of multi-antenna systems is often severely degraded due to the correlation effect between adjacent antennas, (e.g., see [11][12][13]). In particular, the authors in [11] studied the outage probability (OP) of dual hop equally correlated Rayleigh fading channels.…”

“…Taking into account the effect of co-channel interference, Sekulovic et al investigated the outage performance of single hop selection combiner using exponential correlation model [12]. In [13], the performance for partial relay selection of a dual-hop relay system with correlated antennas at each node was studied, where orthogonal space time block coding is employed at the source and the best relay.…”
