摘要

多载波系统对发送端大功率放大器(HPA)引起的互调失真(IMD)和接收端载波频偏(CFO)引起的载波间干扰(ICI)高度敏感。本文分析了在频率选择瑞利衰落信道中，多载波直接序列码分多址(MC-DS-CDMA)系统下行链路中这些损伤引起的误码率(BER)下降。

BER performance degradation of MC-DS-CDMA systems jointly affected by transmitter HPA and receiver CFO in frequency selective fading channels

Multicarrier systems are highly sensitive to the intermodulation distortion (IMD) introduced by high-power amplifiers (HPA) at the transmitter and to the intercarrier interference (ICI) due to a carrier frequency offset (CFO) at the receiver. We analyze the bit-error rate (BER) degradation induced by these impairments in the downlink of a multi-carrier direct-sequence code-division multiple-access (MC-DS-CDMA) systems in frequency-selective Rayleigh fading channels.
