Constant Envelope Binary Ofdm Phase Modulation
نویسندگان
چکیده
In this paper a new approach is presented to alleviate the undesirable effects due to the high peak-to-average power ratio of orthogonal frequency division multiplexing. A class of signaling called OFDM angle modulation is presented. These constant envelope OFDM based signals guarantee a 0dB PAPR thus are well suited for efficient nonlinear power amplification. This paper focuses on binary OFDM phase modulation, which is a special case of OFDM angle modulation.

متن کاملSpectral Containment and Performance Comparison of Constant Envelope OFDM-PM and Standard OFDM
In this paper we study the suitability of constant envelope multi-carrier modulation technique. This technique combines orthogonal frequency division multiplexing (OFDM) and phase modulation (PM) where: (1) PM creates a constant envelope signal which allows high power amplifier to operate near saturation levels thus maximizing power efficiency; (2) OFDM increases robustness to multipath fading....

In this paper we propose an energy efficient OFDM transmission scheme. Two CPM (continuous phase modulation) schemes are introduced to OFDM, keeping in view the constant envelope and continuous phase changing nature of CPM modulation. Energy efficiency of the proposed scheme is investigated by simulating peak to average power ratio (PAPR), and is compare with the conventional OFDM scheme. The i...
