Interference cancellation with high precision, high speed and low computational complexity

Toyohashi University of Technology has developed a self-interference cancellation filter that is indispensable for the realization of in-band full duplex using the same frequency to transmit and receive simultaneously in wireless communications. The developed self-interference cancellation filter can estimate the distortion caused by radio and the distortion of the radio channel with high accuracy and cancel self-interference. Additionally, it can quickly reach the solution of the filter with low computational complexity.
