Abstract :
Smart antennas have been used more and more to establish the SDMA access technique, reducing the spatial interference in a wireless propagation area. The dual of this problem, in the time domain, refers to the intersymbol interference resulting from the multipath components. The article proposes a way to reduce the intersymbol interference through techniques that use the structure of an antenna array.
