Abstract: A MAP decoder may be implemented in parallel. In one implementation, a device may receive an input array that represents received encoded data and calculate, in parallel, a series of transition matrices from the input array. The device may further calculate, in parallel, products of the cumulative products of the series of transition matrices and an initialization vector. The device may further calculate, in parallel and based on the products of the cumulative products of the series of transition matrices and the initialization vector, an output array that corresponds to a decoded version of the received encoded data in the input array.
