Abstract

A novel receiver I/Q imbalance estimation and compensation strategy is proposed for the 3GPP long term evolution (LTE) system using the proposed synchronization signals available in each frame. System architecture and algorithm design for the receiver I/Q imbalance estimation and compensation are described in detail. Algorithm optimization is also discussed for further enhancement of the design. Simulation results indicate that the proposed approach can effectively compensate the receiver I/Q imbalance.
