I/Q IMBALANCE ESTIMATION USING SYNCHRONIZATION SIGNALS IN LTE SYSTEMS

摘要

A method and apparatus perform I/Q imbalance estimation and compensation using synchronization signals in LTE systems. Primary and secondary synchronization signals (P-SCH and S-SCH), which carry synchronization information, are embedded in each LTE frame, and are used for receiver I/Q imbalance estimation. Additionally, the performance may be significantly improved by optimally selecting the training data in I/Q imbalance estimation.
