Abstract
Nonlinear constant envelope digital modulation schemes are attractive in applications where high power efficiency is required. When used in high-rate, band-restricted applications, intersymbol interference (ISI) results and must be compensated to obtain satisfactory error performance. Tomlinson-Harashima precoding has proven attractive in applications with linear modulations such as that in the V.34 standard for high-rate wireline modems. This article presents new results on techniques for precoding of nonlinear constant envelope modulations and their performance analysis in additive noise and fading channels. Substantial performance improvement is obtained over systems without precoding and systems with the Tomlinson type of precoding.
