Latest Patents

Duanyi Wang holds a patent for "MAP decoding for turbo codes by parallel matrix processing." This invention introduces a matrix transform method and circuit that facilitates MAP decoding of turbo codes. The method begins by initializing a forward recursion probability function vector α and a backward recursion probability function vector β. Transition probability matrices Γ(R) and Γ(R) are determined based on each received symbol of the sequence R. The values of α, corresponding to the received R, are calculated using Γ(R). Simultaneously, multiple multiplications on Γ(R) and Γ(R) are performed in parallel. This approach allows for the determination of all values of the backward recursion probability vector β in parallel, significantly accelerating the decoding speed and reducing computational complexity. The circuit is particularly well-suited for implementation in special-purpose parallel processing VLSI hardware architectures, effectively reducing memory requirements and simplifying data accesses and transfers.
