Embodiment Construction
[0027] LDPC decoding is iterative decoding, so there is a maximum number of iterations. When the channel condition is good, it can be decoded correctly with fewer iterations. Therefore, if the channel condition is good, appropriate puncturing is performed. It can ensure correct decoding during the decoding process less than the maximum number of iterations, and at the same time improve the throughput of the system. The performance of LDPC using different code rates is quite different. In the case of puncturing and decoding errors, the accuracy of decoding can be greatly improved by retransmitting a small amount of data that has been knocked out. The present invention fully combines the above-mentioned characteristics of LDPC, and in order to achieve higher spectrum utilization, proposes a method for adaptive low-density parity-check coding control according to the number of LDPC decoding iterations, which is hereinafter referred to as the LDPC-AMC method. The technical conception ...
