LDPC) codes have exhibited capacity approaching performance for large block length, overtaking the performance of turbo codes
While theoretically impressive, LDPC codes present some challenges for practical implementation. In general, LDPC codes have higher encoding complexity than turbo codes both in terms of computational latency and architecture size. Decoder circuits for LDPC codes have a high routing complexity and thus demand large amounts of circuit area.
There has been recent interest in developing analog circuit architectures suitable for decoding.Combining the analog decoding approach with this new encoding technique做数字的同学就没必要看了 |
