“…In [22] antenna selection is done at both transmitter and receiver ends of the bidirectional half-duplex MIMO AF relay network. In [23], [24], the combination of TAS and maximal ratio combining (MRC) at the receiver is used in a one-way AF relay network. In [25], the performance of a dual hop AF MIMO multi-antenna relay network with the best end-to-end antenna selection was considered and compared with the transmit beamforming MRC in [26].…”

Abstract-In this paper, a bidirectional full-duplex amplifyand-forward (AF) relay network with multiple antennas at source nodes is proposed. Assuming that the channel state information is known at the source nodes, transmit antenna selection and maximal ratio combining (MRC) are employed when source nodes transmit information to the relay node and receive information from the relay node respectively, in order to improve the overall signal-to-interference plus noise ratio (SINR). Analytical expressions are derived for tight upper bound SINR at the relay node and source nodes upon reception. Further, closed form expressions are also derived for end-to-end outage probability of the proposed bidirectional full-duplex AF relay network in the Nakagami-m fading channel environment. Although self-interference at the relay node limits the performance of the full-duplex network, the outage performance of the proposed network is better than that of conventional bidirectional full-duplex and half-duplex AF relay networks, due to the selection diversity gain in TAS and diversity and array gain in MRC.Keywords-channel state information, Nakagami-m m m fading channel, self interference, SINR.

“…In order to enhance the diversity gain, MIMO techniques have been introduced into multi-hop relaying systems [3][4][5][6][7][8][9]. In [3][4][5][6], the outage probability and error rate of dual-hop relaying systems with OSTBC have been studied for amplify-and-forward (AF) and decode-and-forward (DF) relaying in Rayleigh and Nakagami-m fading channels.…”

“…As in [3][4][5][6][7][8][9], most researchers have concentrated on AF and DF relaying systems using only either OSTBC or TAS/MRC at all hops. However, in this paper, we focus on the dual-hop DF relaying system with both OSTBC and TAS/MRC, and propose a selective relaying scheme that uses OSTBC and TAS/MRC or vice versa at the first and second hops, respectively.…”

For dual-hop multiple-input multiple-output (MIMO) decode-and-forward relaying systems, we propose a selective relaying scheme that uses orthogonal space-time block code (OSTBC) and transmit antenna selection with maximal-ratio combining (TAS/MRC) or vice versa at the first and second hops, respectively. The aim is to achieve an asymptotically identical performance to the dual-hop relaying system with only TAS/MRC, while requiring lower feedback overhead. In particular, we give the selection criteria based on the antenna configurations and the average channel powers for the first and second hops, assuming Rayleigh fading channels. Also, the numerical results are shown for the outage performance comparison between the dual-hop DF relaying systems with the proposed scheme, only TAS/MRC, and only OSTBC.

“…In both cases ergodic capacity analysis has been taken into consideration. In [9], closed-form cdf, pdf and moment generating function (MGF), expressions of received SNR and SER have been derived for MIMO AF relay network over a Rayleigh fading channel, where transmit antenna selection and maximal ratio combining are used at the source and the destination, respectively, and the relay is equipped with a single antenna [10]. In such an asymmetric fading scenario, the above studies are promising for improving the performance of a wireless communication link.…”

To enhance the reliability of long wireless link, a relay is placed between transmitter and receiver which break the link into two parts: transmitter to relay called 1 st hop and relay to receiver called 2 nd hop; such arrangement is called two hop wireless links. In two-hop wireless communication sometimes 1 st and 2 nd hops are affected by different types of fading called asymmetric fading environment. In this paper we consider four different combinations of Rayleigh and Nakagami-m fading on 1 st and 2 nd hop to observe the profile of combined pdf (probability density function) and cdf (cumulative distribution function). With the help of cdf we determine the variation of outage probability of mixed fading. Finally we plot the SER (symbol error rate) against the SNR (signal to noise ratio) of the 2 nd hop for all possible combinations of the two fading taking the SNR of 1 st hop as a parameter. Although recent literature deals with asymmetric fading environment but in this paper instead of details statistical model of such fading we provide the relative scenario of mixed fading on 2-hop wireless link.
