"The purpose of this study is to investigate some simple receivers for certain bandwidth-efficient modulations that have a constant envelope. Bandwidth-efficient modulations are important due to the increasing demand for communication services and the fact that the available bandwidth is limited. For reasons of efficiency the power amplifier in radio communications equipment is usually operated near power saturation resulting in a non-linear amplification. Any amplitude variations in the input to this amplifier will thus result in AM/AM and AM/PM distortion as well as spectral spreading. It is thus desirable for the input to the amplifier to have a constant envelope. At present, the area of bandwidth-efficient modulations with a constant envelope is the subject of much research"--Introduction, page 1. Radio frequency modulation Receivers and reception.
