Title
Digital compensation of cross modulation distortion in RF subsampling receiver
Abstract
The RF subsampling receiver suffers from nonlinear distortion caused by the front end of the receiver, specifically the low noise amplifier. Strong interferers present in the receiver introduce cross modulation distortion to the desired signal. This paper introduces a compensation method for the cross modulation distortion using digital signal processing techniques. In the proposed method, two signals are down converted using the subsampling receiver and digitized. A joint channel and nonlinearity estimation is then performed for the mitigation of the cross modulation distortion. Simulation results show that the proposed method obtains more accurate estimates compared to existing work, and subsequent compensation is improved as shown by the recovery of the desired signal.
