WebOct 23, 2006 · This paper studies the application of convolutional coding to constant envelope orthogonal frequency division multiplexing (CE-OFDM). The noise at the output of the phase demodulator (in the CE-OFDM receiver) is shown to be approximately Gaussian at high SNR and relatively low modulation indices. WebA class of constant envelope OFDM phase modulated (OFDM-PM) signals is studied. The motivation behind OFDM-PM is to alleviate the high peak-to-average power ratio of conventional OFDM systems.
