The invention discloses a wireless data communication same frequency interference suppression receiver architecture and a working method thereof. When an auxiliary carrier detection circuit detects the arrival of a local radio frequency signal, a control switch and a phase adjuster work; an amplitude detector detects the amplitude of a same frequency interference signal in real time; the phase adjuster makes the phase of a mixed signal coincide with the phase of the same frequency interference signal; a linear subtractor performs a subtraction operation on the mixed signal and the same frequency interference signal with the consistent phases to eliminate the same frequency interference, and an active effect is achieved on the 5G network construction, WIFI interconnection, the Internet of vehicles, the Internet of ships and the Internet of things; and the same frequency interference of a receiver can be eliminated. The same frequency interference of a receiver can be eliminated, and theanti-jamming capability of the receiver is improved.
