Abstract:
1. A process for canceling interference generated by a set interference base stations in a synchronized OFDM communication system that is received in a User Equipment comprising a set of Nrx antennas, the process comprising: performing an OFDM demodulation of the received signal from each Nrx antenna of said UE; monitoring, on each Nrx antenna of said UE, pilot signals generated by one or more present base stations; extracting said pilot signals and establishing a list of existing base station antennas; measuring a channel power of one or more interfering antennas of the set of Nrx antennas; selecting the Nrx-N antennas receiving the most powerful interfering channels; performing a joint detection of N Useful Data Symbol (UDS) streams and (Nrx-N) Interfering Data Symbol (IDS) streams that were demodulated by OFDM demodulation blocks in the User Equipment.
