- Abstract
- In this paper, a new relay selection scheme for decode-and-forward (DF) relay cooperative network with multiple antennas is proposed based on both channel state information (CSI) and transmission scheme by deriving the upper bound on the pairwise error probability (PEP) of the near-maximumlikelihood (near-ML) decoder. It is also proved that the proposed relay selection which selects m (1 <= m <= N) relays from N relays achieves full diversity M(S)M(D) + N M(R) min[M(S), M(D)] regardless of the value of m in the DF relay network consisting of one source, one destination, and N relays with M(S), and M(D) antennas, respectively. Through Monte Carlo simulation, the M(R) error correction performance of the proposed relay selection for various m is shown for the uncoded single-antenna, Alamouti coded, and multiple-input multiple-output (MIMO) DF relay networks.
