Abstract:
1. A method of decoding a coded data block received at a receiver, the method comprising: receiving a first plurality of coded data bits representing the coded data block; determining first soft information values corresponding to respective ones of the received first plurality of coded data bits, wherein each of the soft information values indicates a likelihood of a corresponding coded data bit having a particular value; attempting to decode the coded data block using the first soft information values; compressing the first soft information values using a compression scheme to map a plurality of ranges of uncompressed soft information values to a respective plurality of compressed soft information values, wherein said compression scheme is either a non-linear compression scheme in which the ranges are of unequal size or the compression scheme is a linear compression scheme in which the ranges are of equal sizes; causing the compressed first soft information values to be stored in a data store; receiving a second plurality of coded data bits representing the coded data block; determining second soft information values corresponding to respective ones of the received second plurality of coded data bits; retrieving the compressed first soft information values from the data store; decompressing the retrieved first soft information values; combining the decompressed first soft information values with the second soft information values; and attempting to decode the coded data block using the combined soft information values.
