Constant Envelope DCT based OFDM System with M-ary PAM Mapper over Fading Channels

by Rayan Hamza Alsisi and Raveendra Kolarramakrishna Rao

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 1, Page # 252–260, 2018; DOI: 10.25046/aj030131

Abstract:

Constant Envelope Discrete Cosine Transform based Orthogonal Frequency Division Multiplexing (CE-DCT-OFDM) system with M-ary Pulse Amplitude Modulation (PAM) mapper is considered. In the system phase modulation is used to achieve constant envelope signals that have 0 dB Peak-to-Average-Power Ratio (PAPR). Transmission of such signals permit high power amplifiers in the system to operate with maximum…
