Abstract

The invention discloses a co-frequency co-time full duplex separation method for a frequency domain signal of a receiver in wireless data communication. An auxiliary carrier detection circuit indicates a carrier signal ID, arrival and end time of the carrier signal, a code element width of the carrier signal, and a sample adjustment algorithm, records an accurate signal time, determines phase andamplitude of an initial segment of signal, and performs operation on the signal according to a designated method so as to separate co-frequency wireless carrier signals, so that the anti-interferenceof the wireless receiver is improved. Co-frequency co-time full duplex wireless signal transmission is realized in data communication.
