Abstract
An apparatus and method for high throughput unified turbo decoding comprising loading data from a first data window; computing a first forward state metric using the data from the first data window; storing the first forward state metric in a memory; computing a first reverse state metric using the data from the first data window; storing the first reverse state metric in the memory; and computing the log likelihood ratio (LLR) of the first forward state metric and the first reverse state metric. In one aspect, the above-mentioned steps are repeated with data from a second data window. In another aspect, extrinsic information for the first data window associated with the unified turbo decoding is computed.
