Abstract
The I/Q mismatches in wideband receivers designed for multichannel reception can be frequency-dependent and limit their image rejection performance to an unacceptable level. An adaptive signal-image separation system is proposed to correct the frequency-dependent I/Q mismatches in the digital domain. Simulation results verifying the proposed method are given
