摘要

补偿非线性失真在低功率和高功率卫星通信、磁记录和多载波系统(如OFDM和离散多音(DMT))中很有意义，其中非恒定模量传输增加了峰值-平均功率比。提出了一种基于模块算法的数字零强迫(ZF)预失真器，用于均衡非线性Volterra信道。

Modulo pre-equalization of nonlinear communication channels

Compensating for nonlinear distortions is of interest in low- and high-power satellite communications, magnetic recording, and multicarrier systems such as OFDM and discrete multi-tone (DMT) where non-constant modulus transmissions increase the peak-to-average power ratio. A digital zero-forcing (ZF) predistorter, based on module arithmetic, is developed to equalize nonlinear Volterra channels whose estimates are available at the transmitter.
