Author_Institution :
Univ. of South Florida, Tampa, FL
Abstract :
In this paper, IQ gain imbalance for OFDM based multi-carrier modulation techniques is studied. The effect of gain mismatch in IQ modulator will be investigated on the system and receiver performance. Estimation and measurement of IQ gain mismatch at the receiver using baseband digital signal processing techniques will be discussed
