Indoor multi-base stations system with simultaneous transmission using OFDM adaptive array antenna

We propose to set an OFDM adaptive array on a mobile terminal in order to collect the signals received from multi-base stations efficiently in an indoor wireless system. By doing so, the system will obtain some diversity gain when the received signals contain the same data. Moreover, when they contain different data, the mobile terminal is capable of mitigating the interferer waves and thus obtaining the desired signal. The performance of the proposed system is evaluated by computer simulations and the possibility of constructing a system without the use of frequency assignment or time assignment in wireless networks is discussed
