IQ imbalance estimation and compensation in receiver system
The aim of this work is to study the in phase (I) and quadrature (Q) imbalance problem in the receiver (RX) system. In this study, we use the characteristics of I and Q signals in time domain, which have the same amplitude and the phase between the two paths is 90 degrees to estimate the I and Q gain and phase imbalance components. Simulation results demonstrate that the proposed method can estimate the in phase and quadrature gain and phase mismatch parameters to compensate the receiver (RX) IQ imbalance problem.
