In this paper, we investigate the performance of the multi-input-multi-output (MIMO) relaying scheme, which combines the Alamouti code with fixed decode-and-forward (DF) protocol. Based on the relationship between the overall signal-to-noise ratio (SNR) of the system and that of the weakest hop, the closed-form expressions of outage probability and bit error probability for MPSK are derived. The analysis...
In this letter, we investigate the performance of distributed switch-and-stay network, an appropriate solution for low-complexity cooperative relaying applications, under adaptive transmission. Under Rayleigh fading channels, we are able to derive the closed-form expression of the occurrence probability, outage probability, bit error probability and achievable spectral efficiency of the system. Numerous...
We propose and analyze a distributed switch and stay combining network with selection relaying with an aim to reduce the complexity at the destination as well as to make efficient use of the degrees of freedom of the channels by exploiting a limited feedback signal from the destination. In particular, whenever the currently connected link (either from the source or from the best relay) to the destination...
