“…Considering the case that all nodes employ multiple-antennas, in [4], Chen et al derived expressions for the SER and the outage probability of MIMO CSI-assisted AF cooperative single-relay networks using OSTBC subject to Rayleigh fading. Also, assuming that all nodes use multiple-antennas and the network undergoes Rayleigh fading, in [5], asymptotic analysis of the SER of MIMO cooperative AF single-relay networks with OSTBCs is provided. By considering a specific STBC, in [6], performance analysis for MIMO cooperative AF singlerelay networks with Alamouti STBC experiencing Rayleigh fading, wherein each node has multiple-antennas, has been introduced.…”

In this paper, the performance of a dual-hop multiple-input multiple-output (MIMO) cooperative multiplerelay network using orthogonal space-time block coding (OS-TBC) transmission is examined. The fading environment is modeled as independent, not identical distributed (i.n.i.d.) Nakagamifading. Also, we consider the case that each terminal in the network has multiple-antennas, the relays operate in channel state information (CSI)-assisted amplify-and-forward (AF) relaying mode, and the direct transmission from the source to the destination is applicable. In particular, we derive a closedform expression for the moment generating function (MGF) of the instantaneous signal-to-noise ratio (SNR). Utilizing this derivation, we can analyze the SER performance of the considered system for -ary phase shift-keying ( -PSK) and -ary quadrature amplitude modulation ( -QAM) scheme. Also, the outage performance of the considered relay networks is evaluated. We further investigate the cooperative diversity behavior by deriving asymptotic approximations for the outage probability and the SER. Finally, numerical results are provided showing very close agreement between the analytical results and the Monte-Carlo simulations.

“…However, the pure diversity systems have low transmission efficiency. Thus spacetime block codes (STBC) were taken into MIMO AF relaying systems to gain the data rate enhancement [7], [8], [10]. From the analysis in [7], the data rate and detection complexity of MIMO relaying systems with STBC are mostly dependent on the forms of STBC.…”

Using a spatial multiplexing transmission scheme can improve the data rate in multiple-input multiple-output (MIMO) relaying systems, while making signal detection more difficult at receivers. Aiming at lowering the computational complexity of the receiver, this paper proposes a maximum likelihood combining (MLC) algorithm for spatial multiplexing MIMO amplify-and-forward (AF) relaying systems in Rayleigh flat-fading environment, which is implemented before maximum likelihood (ML) detection. The combining signal and equivalent channel are opportunely designed based on ML rule in the MLC algorithm. We also formulate the diversity gain of the systems that employ the MLC algorithm mathematically, induced by the Chernoff bound of pairwise error probability (PEP). An upper bound on the symbol error probability (SEP) for MLC algorithm with multiple modulations is given as well based on the derived bound of PEP. Moreover, the complexities of ML receivers adopting the MLC algorithm and the conventional vector combining (VC) algorithm are analyzed. Numerical simulations indicate that systems with MLC algorithm achieve the same performance while consuming lower computational complexity compared to that with VC algorithm.Index Terms-Combining algorithm, spatial multiplexing, multiple-input multiple-output, amplify-and-forward, maximum likelihood detection, pairwise error probability.
