Sensitivity of a MC-CDMA Beyond 3G System to RF

mathieu.desnoes @ cea.fr The MC-CDMA transmission technique is seen as a candidate for beyond 3G systems. It benefits from the high bandwidth efficiency of multi-carrier systems and the flexibility and granularity offered by CDMA for resources allocation. In the framework of the IST MATRICE European project, a MC-CDMA beyond 3G system has been defined and extensively studied. This paper describes the sensitivity of this system to receiver non-linearity, I&Q mismatch, carrier frequency offset and phase noise. Simulation results show that the higher efficiency of future B3G implies severe constraints on RF front-end. I
