Patent ID: 8184750

Claim:
A method of selection of Logarithmic Likelihood Ratio (LLR) code blocks based upon first and second code words each containing a respective plurality of indexed code blocks, wherein each of said plurality of indexed code blocks containing a plurality of Minimum Mean Squared Error (MMSE)-LLR values, the method comprising: generating an indexed composite code word of a first data stream, wherein said generating includes: decoding symbols of a first indexed code block from said first code word; determining whether a reliability metric of said decoded symbols of said first indexed code block from said first code word satisfies a quality threshold; if said reliability metric satisfies said quality threshold, storing a plurality of Successive Interference Cancellation (SIC)-LLR values of said second code word within an indexed code block of said indexed composite code word, wherein said SIC-LLR values correspond in index to said first indexed code block, and wherein said SIC-LLR values are derived from said decoded symbols of said first indexed code block; and if said reliability metric fails to satisfy said quality threshold, storing in said indexed code block of said indexed composite code word a plurality of MMSE-LLR values of a second indexed code block of said second code word, wherein said MMSE-LLR values of the second indexed code block correspond in index to said first indexed code block.
