Frequency Independent IQ Imbalance Estimation and Compensation

Chapter
Part of the SpringerBriefs in Electrical and Computer Engineering book series (BRIEFSELECTRIC)

Abstract

For narrow band systems, the IQ imbalance can be assumed to be frequency independent. In this chapter, we look at the frequency independent IQ imbalance estimation and compensation. We start from simple RX only IQ imbalance estimation and compensation, then discuss joint TX and RX IQ imbalance compensation and estimation. After that we discuss the estimation and compensation of IQ imbalance when there is frequency offset. At last, we look at the IQ imbalance for multiple antenna systems.
