Performance of a system is determined by the probability of error of the channel. In this paper, the error probability of cooperative relay channel is analyzed for Quadrature Phase Shift Keying (QPSK) using simple linear block coding. Focusing on a network with single source to destination with one relay station, the upper bound of symbol error rate (SER) is derived. A power control scheme is also proposed to improve the performance of the system. Computer simulations confirm the presented mathematical analysis.
