Figure 7From: Alamouti-coded decode-and-forward protocol with optimum relay selection and power allocation for cooperative communicationsSimulated SER of Alamouti-coded decode-and-forward protocol with optimum relay selection cooperative communications. Different transmission power levels: P1 and P2. (a) Fixed channel variances with different SNR values. (b) High SNR regime with different channel variances. (c) Low SNR regime with different channel variances.Back to article page
