This paper studies the multiple antenna system is a kind of cognitive radio can achieve full interference alignment method of multiplexing gain, sender in multiple users and multiple users topology results at the receiving end, the user system interference to primary user system to produce at the same time, also cause interference between each other, which reduces the primary user system and the size of user system, also can affect the user's system can't normal communication; This method is based on the interference to primary user system under the condition of limited power, maximize user system capacity; Through the analysis can see, interference alignment method through alignment interference subspace, can spare the relative number of signal subspace, the subspace can be used to transport the user system information and useful information of user's system, so as to eliminate the interference effect; The simulation results show that this method is compared with the previous beam forming algorithm, and can get more transfer rate, improve the capacity of second user's system.
