Modulation and Demodulation Technique of Constant Envelope OFDM
IMCCC '14: Proceedings of the 2014 Fourth International Conference on Instrumentation and Measurement, Computer, Communication and ControlThe theory of constant envelope orthogonal frequency division multiplexing (CE-OFDM) is analyzed in this paper, along with the introduction of the implementation method of CE-OFDM technique. Besides, the modulation and demodulation process is simulated ...
Tone reservation to reduce the envelope fluctuations of multicarrier signals
In this paper we propose a method for reducing nonlinearity distortion by limiting the envelope fluctuations of an OFDM signal. The method is based on tone reservation, and the free tones are assigned in a way to limit the variations of the ...
Spectral precoding for constant-envelope OFDM
Spectrally precoded orthogonal frequency-division multiplexing (OFDM) and constant-envelope OFDM (CE-OFDM) are two modified OFDM formats that enhance the signaling features of OFDM, while allowing for the efficient implementation by discrete Fourier ...
