  3. 3. Spectrally Efficient Continuous Phase Modulation

    Author : Tommy Svensson; Chalmers University of Technology; []
    Keywords : spectrum efficiency; Laurent decomposition; additive white Gaussian noise AWGN ; trellis coded modulation TCM ; non-linear channels; continuous phase modulation CPM ; maximum likelihood sequence detection MLSD ; distance spectrum; convolutional codes;

    Abstract : Spectrally efficient continuous phase modulation (CPM) systems and generalizations of CPM for wireless links are considered. Continuous phase modulation defines constant envelope phase codes, which are advantageous when using non-linear amplifiers. READ MORE
