摘要

卫星系统中使用的行波管放大器(twta)和载波频率偏移(CFOs)产生的载波间干扰(ICI)对多载波系统有显著影响。为了降低ICI，提出了一种基于失真-信号功率比(DSR)测量的部分发射序列(PTS)方案的改进版本。蒙特卡罗仿真结果表明，该系统在误码率(BER)、有效信噪比(ESNR)和互补累积分布函数(CCDF)方面优于传统PTS。

Efficient ICI reduction technique for OFDM systems distorted by TWTA and CFO

Multi-carrier systems are significantly affected by inter-carrier interference (ICI) produced by both travelling wave tube amplifiers (TWTAs) utilized in satellite systems and carrier frequency offsets (CFOs). To reduce the ICI, an improved version of the partial transmit sequences (PTS) scheme is proposed based the distortion-to-signal power ratio (DSR) measurements. Monte Carlo simulation results demonstrated that the proposed system outperforms the conventional PTS in terms of bit error rate (BER), effective signal-to-noise ratio (ESNR) and complementary cumulative distribution function (CCDF).
