Intercell Interference Mitigation for Uplink OFDM Code Division Multiplexing
Laurent Cariou, Jean‐François Hèlard, Jean‐Yves Baudais · 2006
In this paper, we investigate the robustness of the spread spectrum multi-carrier multiple access (SS-MC-MA) technique in uplink multicellular systems. In a first step, a statistical characterization of the intercell interference is carried on to model it for BER performance simulations. Then, the impact of the intercell interference on such a scheme is evaluated and the robustness of SS-MC-MA system by mitigating those interferences thanks to frequency allocation, channel coding and spreading gain is optimized
