  3. 3. Spectrally Efficient Continuous Phase Modulation

    University dissertation from Chalmers University of Technology

    Author : Tommy Svensson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Informationsteknik; Information technology; continuous phase modulation CPM ; convolutional codes; trellis coded modulation TCM ; maximum likelihood sequence detection MLSD ; distance spectrum; non-linear channels; additive white Gaussian noise AWGN ; spectrum efficiency; Laurent decomposition;

    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
