WCDMA 시스템 직접변환 단말기 수신기에서 DC 오프셋에 의한 성능영향 = The Effects of DC Offset on the Performance of Direct-Conversion Mobile Receiver in WCDMA System

다국어 초록 (Multilingual Abstract)

This paper describes what brings about DC offset and the impact or the DC offset on the performance or direct-conversion mobile receiver in WCDMA system. The performance degradation of $E_{b}/N_{o}$ due to the DC offset is presented through simulation result. Direct-conversion RF Transceiver which has the function of DC offset control is implemented and then applied to the WCDMA test-bed for the performance evaluation. The receiver performance degradation of $E_{c}/I_{o}$ is evaluated and analyzed by varying DC offset value. The practical test showed the minimum requirement of DC offset value to meet system performance.
