Methods of, and apparatus for, producing code words |
摘要 |
Datawords encoded using a first-order Reed-Muller code are decoded using a Fast Hadamard Transform (FHT). Where the dataword is known to comprise a number of unused bits at one end, the soft decisions of the codeword are reordered. Majority polling is then performed on groups of the soft decisions to produce a series of soft decisions which make up a new codeword. The new codeword is then decoded using an FHT of lower order than the FHT applicable to the originally received codeword.
