In this paper, the authors study 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.
