Abstract
The fifth generation (5G) wireless network technology is to be standardized by 2020, where main goals are to improve capacity, reliability, and energy efficiency. Constant envelope orthogonal frequency division multiplexing (CE-OFDM) is a technique to modify the OFDM signal with high peak-to-average power ratio (PAPR) to a constant envelope zero decibel PAPR waveform, in order to minimize energy consumption in future wireless communication systems (5G). The conventional CE-OFDM uses inverse discrete Fourier transform (IDFT) to calculate the signal time samples before feeding them to the phase modulator. In this paper, the performances of the CE-OFDM are studied in terms of the BER over AWGN channel and frequency-selective fading channel.
