post-doctorat au CNAM-Paris : co-channel multi-user interference elimination Post-Doc DeadLine: 30/11/2009 christophe.alexandre@cnam.fr http:// Title : post-doc at CNAM-Paris : co-channel multi-user interference elimination Post doctoral researcher / research engineer Context : A postdoctoral fellow position is opened at LAETITIA research team, CNAM Paris. In the context of radio-communication systems using OFDM modulation, such as 802.16, 3GPP/LTE, the aim of the proposed work is to evaluate the computational complexity and architecture of the algorithm proposed in [1] . The candidate will also participate to the development of a dsp based demonstration plateform. The algorithm improves the robustness of the communication systems against co-channel multi-user interference, by cancelling or mitigating interferer symbols contributions along the OFDM frame, without a-priori knowledge of the type of interferer. It takes advantage of the properties of OFDM modulation in systems with receivers using multiple reception antennas, and is based on a basis expansion model taking into account physical limitations of the propagation channel. First simulations have shown that using the proposed algorithm, the system to be less sensitive to the multi-user interference. During this work, advanced and novel solutions will be also studied.
