摘要

(AMC) scheme is modulated and encodes in advanced, adaptive, the bit error rate and parity matrix (PCM) are suitable for for low-density checksum (LDPC) code according to modulation format and variable iterative receiver. The adaptability of degree distribution and PCM, the SNR needed for being minimized by design heuristic optimization shift (EXIT) trajectory analysis via extrinsic information and decode for finite iteration. This method utilizes dynamic window decoding by generating the quasi-cyclic LDPC convolutional encodings of PCM for Space Coupling. This method provides a kind of mode also jointly to optimize label decoding complexity high-order multidimensional simplex. The modulation format and variable iterative decoding that the problem uses a large amount of different LDPC codes different are also processed to be adapted to across repeat count with linearly related PCM to keep using public generator matrix. The problem of PCM adaptations can be improved the decoding of convergence rate belief propagation and reduce error floor.
