Abstract :
I and Q channel phase and gain mismatches are of great concern in communications receiver design. We carry out a detailed performance analysis of the blind-source separation (BSS) based imbalance compensation structure. The results indicate that the BSS structure can offer adequate performance for most communication systems. Since the compensation is carried out before any modulation specific processing, the proposed compensation method works with all standard modulation formats.
