Reconfigurable Antenna Array Architecture for OFDM Receivers
Overview This paper deals with the problem of the multi-antenna array receiver optimization for OFDM-based wireless LANs. In fact, it has been stated that the best algorithm and even its key parameters depend deeply on the working environment. For these choices, two solutions are here proposed: the classical bayesian channel classification and a fuzzy inference-based selection for a single antenna. After that, the paper exploits the receiver spatial diversity by using a Fuzzy Logic System (FLS). Conducted simulations show that the performance of the fuzzy inference-based classifiers can reach the optimum bayesian results at good SINR, while the proposed FLS exploits successfully the array at reception when the errors of the single antenna classifier are over a certain threshold.
