Joint Blind Compensation of Inter-Block Interference and Frequency-Dependent IQ Imbalance
Xi Zhang, Teruyuki Miyajima · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2015
In this letter, we propose a blind adaptive algorithm for joint compensation of inter-block interference (IBI) and frequency-dependent IQ imbalance using a single time-domain equalizer. We combine the MERRY algorithm for IBI suppression with the differential constant modulus algorithm to compensate for IQ imbalance. The effectiveness of the proposed algorithm is shown through computer simulations.
