Error correcting coding schemes for a broadcast channels

摘要

Binary maximum slope (MS) convolutional codes are introduced for Gaussian broadcast channel. For 2-user broadcast channel convolutional encoder maps 2 uniformly random messages to single codeword. For transmission over AWGN channel code bits are mapped into different q - ry QAM symbols while satisfying broadcast signal to noise constraints. Simulation results for signal-code construction with MS convolutional code are presented. It is shown, that the code choice makes a tradeoff between df and α.
