| Abstract(in English) | The development of direct receiver techniques is expected to become a solution for future wideband or multiband wireless systems based on software defined radio. In this paper, direct conversion receiver using 6-port device is studied. We examine the impact on performance of a direct conversion receiver due to imperfect phase imbalance. We propose an I/Q channel regeneration using a real time early-late phase compensator to estimate a phase error in direct receivers. The proposed technique is shown to mitigate the impact of AWGN and improves performance especially at low SNR channel condition. The bit-error-rate performance of our proposed systme is about 4dB better than conventional systems under 45-55 degrees phase imbalance. |
