摘要：

The I/Q mismatches in a quadrature radio receiver designed for multi-channel reception can be frequency-dependent and limit its image rejection performance to an unacceptable level. In this paper, an adaptive signal-image separation system is proposed to correct the frequency-dependent I/Q mismatches in digital domain. Simulation results verifying the proposed method are given.
