Abstract :
In this work, a comparison between the performance of a single antenna and a multiple antenna system which have to identify two similar OFDM signals, is provided. Numerical simulations have shown that multiple antenna systems allow to obtain better performance with respect to single antenna systems with a significant reduction of the observation time, also in multipath environment.
