  2. 1. Joint Source-Channel Coding using Trellis Coded CPM

    Author : Zihuai Lin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iterative decoding; serially concatenated CPM; punctured ring convolutional codes.; trellis coded quantization; turbo codes; turbo trellis coded modulation; soft decoding; ring convolutional coded CPM; continuous phase modulation; Joint source channel coding;

    Abstract : The thesis investigates Joint Source and Channel Coding(JSCC) using combined Trellis Coded Quantization (TCQ) and coded modulation. First we investigate a JSCC scheme using combined TCQ/Trellis Coded CPM (TCQ/TCCPM). Based on the BCJR algorithm for trellis coded CPM, we derive an optimal soft decoding algorithm for the considered systems. READ MORE

  7. 5. Spectrally Efficient Continuous Phase Modulation

    Author : Tommy Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
