The design of reliable wireless communication systems in the unlicensed frequency band has become an emerging research hotpot to improve the utilization efficiency of spectrum resources and shorten the development period with the increasing shortage of spectrum resources. This work proposes a reliable wireless communication system in ISM band based on new wireless channel clearing technique and a priori self-interference suppression method. In order to address the inherent self-interference problem of the proposed system, this work proposes a priori information-assistant radio frequency AD clearing strategy, which avoids the influences of self-interference on the bit error rate and loop tracking performance of the communication system. Finally, the performance of the proposed system is verified through software and hardware simulations and experiments.
