Abstract :
Joint Source and Channel Coding (JSCC) scheme using ring convolutional coded Continuous Phase Modulation (CPM) is investigated. The channels under this investigation are the Additive White Gaussian Noise (AWGN) channel and the Rayleigh fading Channel. Optimal soft decoding for the proposed JSCC scheme is studied. The soft decoder is based on the A Posteriori Probability (APP) algorithm for trellis coded CPM with ring convolutional codes. The novelties of this work are the development of a JSCC scheme using ring convolutional coded CPM, the use of a soft decoder and the APP algorithm for the combined systems.
