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