Pipeline architecture for maximum a posteriori (MAP) decoders

摘要

The application relates to sliding-window maximum a posteriori MAP decoding. In a MAP decoder, a method for determining binary states of received signals comprises receiving data bits, each bit being accompanied by at least one parity bit, providing each received data bit and parity bit with an address (16a) of a calculated extrinsic value (14a) and associated intrinsic data and storing the data bits, the parity bits and the extrinsic value address in a first memory (12).
