It has been verified cooperative communication technology is an effective way to achieve physical layer security. Recently, people paid much attention to the cooperative networks with buffering relay, which can get significantly performance advantage. In this paper, we investigate the secure problem in amplify-and-forward buffer-aided cooperative networks. We modeled the AF secure cooperative network...
In this paper, multiple-symbol-differential-detection (MSDD) of M-PSK with cooperative diversity reception is examined. We analyzed the performance of amplify-and-forward (AF) cooperative MSDD scheme with one relay, and obtained the upper bound of bit-error-rate (BER), which can be used into the environment of arbitrary N (denotes the number of symbols in the observation interval) and arbitrary M-ray...
In this paper, the performance comparison of differential detection and coherent detection with imperfect channel estimation in AF cooperative communication is examined. We consider the real environment with channel estimation error, and utilize the average bit-error-rate (BER) performance of the two detection schemes to derive the BERs' crossover point between channel estimation error and signal-...
