Latest Patents

Hykong Chang holds a patent titled "Acceleration of convergence rate with verified bits in turbo decoding." This patent describes a system and method for accelerating the convergence rate of turbo decoding by verifying bits in data frames whose CRC shows no bit errors. Verified bits are translated to bound nodes on a trellis of nodes representing a sequence of bits of the encoded code block. The verification of all bits signals a stop condition, allowing decoding iterations to be terminated. Furthermore, state transition metrics are limited when a node is adjacent to a bound node, which accelerates convergence by eliminating impossible state transitions. The patent also discloses a scheme to detect bit errors when the code block contains unframed data or partial data frames. This bit error detection scheme utilizes a recursive encoder to establish end node status, thereby enhancing the recognition of convergence rate when combined with other stop conditions.
