Abstract
A major drawback with an orthogonal frequency division multiplexing (OFDM) system is its high peak-to-average-power ratio (PAPR). Here, the use of multiamplitude continuous phase modulation (CPM) signals for reducing PAPR is proposed and investigated. In this method, two signal points represent the same information and the one that minimises PAPR is chosen. The concept of partial transmit sequences (PTS) is used to select the best signal points. It is shown through simulations that the proposed scheme reduces the PAPR of 128-carrier OFDM-CPM signals by >4 dB
