Paper Abstract

Continuous Phase Modulation (CPM) waveforms offer some very appealing characteristics such as constant envelope and bandwidth efficiency. Orthogonal Frequency Division Multiplexing (OFDM) is a popular technique used for digital data transmission due to its low computational complexity and simple equalization process. One of its main drawbacks is the very large peak power to average power ratio (PAPR) which requires the use of very linear power amplifiers (PA) and a large power back-off into the PA. In recent years a variant of OFDM has been developed known as constant envelope OFDM. This paper will compare the bandwidth efficiency and performance of CPM and constant-envelope OFDM waveforms.
