With the advent of 6G era, due to the similarity between communication system and perception system, the dual-function system integrated sensing and communication (ISAC) is proposed and becomes a hot research topic. But different from the traditional communication system, ISAC system is faced with more complex environment, and the problems to be solved have been shifted. In order to improve the performance of the system, the self-interference problem of ISAC system is studied in this paper. The self-interference of ISAC system mainly comes from other transmitters other than the target transmitter, so we study the signal sent by the transmitter and the signal received by the receiver, and strive to maximize the target direction and signal energy on the channel through precoding at the transmitter, improve the signal-to-noise ratio of the system, and finally achieve the purpose of improving the performance of the system.
