摘要

摘要: 该文对下行无线通信信道中MC-CDMA系统的载波误差性能进行了研究。对接收判决器的输入信噪比(SNR)和判决误码率(BER)进行了详细的理论分析和数值模拟。结果表明，MC-CDMA对载波频率偏移十分敏感，系统性能随载波数量的增加而迅速下降；在最大载荷下，载波相位抖动导致的性能下降与载波数无关。

Abstract: This paper presents the effect of carrier phase error on MC-CDMA performance in downlink mobile communications. Signal-to-Noise Ratio (SNR) and Bit-Error-Rate (BER.) is analyzed taking into account the effect, of carrier phase error. It is shown that the MC-CDMA system is very sensitive to a carrier frequency offset, and the system performance rapidly degrades and strongly depends on the number of carriers. For a maximal load, the degradation caused by carrier phase jitter is independent of the number of the carriers.
