Abstract :
Multi-carrier code division multiplex access (MC-CDMA) is one of the best candidates for the future broadband wireless multimedia communication systems. This work investigates the influence of channel estimation on the performance in MC-CDMA systems and the optimum pilot-to-data power ratio (PDR) is derived. Numerical results are presented and our conclusion is followed.
