“…It produces multiuser diversity and is a viable solution when the direct path from source to destination is not available due to heavy shadowing. The performance of MRN has been investigated in several literature with single antenna nodes (see eg: [1]- [4]). The authors in [1] analyzed MRN system for Rayleigh fading channels and the effect of the interference was discussed in [2].…”

“…The authors in [1] analyzed MRN system for Rayleigh fading channels and the effect of the interference was discussed in [2]. The outage probability was derived for the Nakagami-m channel by the authors in [3] while those in [4] investigated the average SER for the same system. All of the above mentioned analyses are limited to single antenna nodes and to CSI-assisted relaying.…”

Abstract-This paper presents the performance analysis of multi-user scheduling for channel state information (CSI)-assisted and fixed gain AF relaying with antenna correlation. We consider a source equipped with multiple correlated antennas communicating with multiple users via a relay which has dual correlated antennas. The system performance degrades with the spatial correlation. Hence we derive the exact closed form solutions to outage probability, average symbol error rate (SER) and generalized higher moment of the signal-to-noise ratio (SNR) to quantify this detrimental effect. The ergodic capacity is also analyzed. To understand the insight system performance behavior and the diversity gain, we present a high SNR analysis. The analytical results are verified with the Monte Carlo simulations at the end.

“…Because of ignoring direct links between source and destinations and the half duplex nature of relay node, the diversity order and spectral efficiency obtained were not satisfactory. Then, the average symbol error rate (SER) of the same model was presented and studied in . Authors in studied the opportunistic direct links in a multiuser cooperative network with decode‐and‐forward (DF) relaying protocol.…”

In this paper, we examine the impact of antenna correlation on transmit antenna selection with receive maximal ratio combining (TAS/MRC) in multiple-input multiple-output multiuser underlay cognitive radio network (MIMO-MCN) over a Nakagami-m fading environment. The secondary network under consideration consists of a single source and M destinations equipped with multiple correlated antennas at each node. The primary network composed of L primary users, each of which is equipped with multiple correlated antennas. For the considered underlay spectrum sharing paradigm, the transmission power of the proposed secondary system is limited by the peak interference limit on the primary network and the maximum transmission power at the secondary network. In particular, we derive exact closed-form expressions for the outage probability and average symbol error rate of the proposed secondary system. To gain further insights, simple asymptotic closed-form expressions for the outage probability and symbol error rate are provided to obtain the achievable diversity order and coding gain of the system. In addition, the impact of antenna correlation on the secondary user ergodic capacity has been investigated by deriving closed-form expressions for the secondary user capacity. The derived analytical formulas herein are supported by numerical and simulation results to clarify the main contributions.
