摘要：To achieve the multiuser diversity and cooperative diversity, a two source destination pair is consideredfor cooperative communication system. Hybrid Decode Amplify Forward (HDAF) Relaying Protocol improves thesystem performance by combining the merits of both Amplify Forward (AF) and Decode Forward (DF) protocols isused. The fast and efficient Parallel Shift Water Filling (SPWF) algorithm can minimize the total power, based on theoutage probability constraint. In the conventional algorithms, the solution is obtained by an iterative binary searchingand Lagrange Multiplier searching process. In contrast, PSWF Algorithm removes the iterative searching process. Itexecutes the PSWF only once, and then directly calculates the final solution with the parallel shift property as anenabling mechanism. Numerical analysis is used to compare the various relaying protocols based on outage probabilityand Bit Error Rate.
