Performance improvement in coded cooperation systems using FSK/PSK modulation
09 April 2009
In this paper, coded user cooperation systems are integrated with combined frequency and phase modulation FSK/PSK. Bit error performance of the proposed scheme is evaluated by computer simulations in quasistatic Rayleigh fading channels. Simulation results show that the FSK/PSK modulation provides much better error performance than the classical MPSK modulation in coded cooperation systems.
