... H 1 and H 2 is an i.i.d. complex random variable with zero mean and unit variance. Consid- ering that the distance between BS and the MSs is usually larger than that between RS and BS, a relevant ... 0, we can see that CS2-MMSE/RDP can achieve an excellent tradeoff of complexity and performance. However, CS1-MMSE/RDP scheme sacrifices not much complexity for much better performance than o...

... alloca- tion schemes. For transmission power among nodes, we employed the two power control schemes introduced in Section 4, and also uniform power transmission among relays, that is, P 1 = P/2andP 2,r = ... opportunistic relaying. Therefore, the whole transmission power during the second phase is transmitted by the relay with the best channel conditions. We analyzed the SER performan...
