Abstract:
1. A method, performed by a receiver device, of decoding a received communication signal comprising turbo encoded data, the method comprising: receiving a signal comprising a turbo encoded block of data; dividing the turbo encoded block of data into contiguous sub-blocks of data; dividing the turbo encoded block of data into contiguous and partially overlapping segments, each segment including a number of contiguous sub-blocks and including at least one sub-block also included in each adjacent segment; and producing decoded output data by decoding each of the segments in parallel using a sliding window process, wherein, for each of the segments being decoded in parallel, the sliding window process is successively performed on consecutive ones of sub-blocks included in the respective segment, and is performed using a sliding window of a size that is equal to a size of the sub-block on which the sliding window process is being performed.
