先前的工作已经完成在[1],[2],[3],[4],其重点是系统级描述的用户合作的概念。它专注于物理层问题,任何的期待更高层次的开销将收益相比可以忽略不计。重点合作的类型,是活跃用户的合作,即。,users who have information of their own to send and thus do not want to simply be another user’s relay. Cooperative relaying is an effective technique to combat multipath fading, improve system capacity and enhance the coverage. Initially, capacity analysis of Gaussian relay channel was comprehensively studied in [6]. For network scenario, capacity has been analyzed in [7]. Coding strategies that exploit node cooperation has been developed in [8] for relay networks. Outage probability of multi-hop amplify and forward relay system has been analyzed in [9]. In [10], closed form expressions of average bit error rate, amount of fading and outage probability have been derived for Rayleighfading channel where relay works in non-regenerative mode and destination performs equal gain combining. An overview of various cooperation schemes and issues related to their implementation has been discussed in [11]. Various power allocation strategies for non-generative relay network have been studied in [12]. In [13], closed form expressions of outage probability and bit error rate (BER) for binary phase shift keying (BPSK) are derived for the case where communication between source and destination is supported by multi antenna relay and both relay and destination perform maximum ratio combining (MRC) of signals in Rayleigh fading channel. Outage probability and average error rate of two-hop multi antenna relay based system for the case when relay performs selection combining (SC) of signals and destination performs MRC of signals are analyzed in [14] and [15], respectively. Closed form expressions of BER have been established in [16] for two-hop multi antenna cooperative relay network in Rayleigh fading channel. Here, destination performs selection combining of signals received from source, relay and relay performs selection or MRC combining of signal. In [17], analytical expressions of average received SNR, outage BER and channel capacity has been established for the case when source and relay are communicating with multi-antenna destination in Rayleigh fading channel. Closed form expression of outage probability has been derived in [18]; here, communication between source and destination is supported by two multi-antenna relay nodes.
