Latest Patents

One of his latest patents is titled "Turbo decoder employing simplified log-MAP decoding." This invention focuses on a turbo decoder that iteratively decodes a received, encoded signal using a simplified log-maximum a posteriori (SMAP) decoding algorithm. The SMAP algorithm calculates reliability information as a log likelihood ratio for a log-MAP algorithm, utilizing a reduced set of path metrics that are recursively updated based on maximum likelihood recursion. This advancement allows for updated extrinsic information for subsequent decoding derived from the log likelihood ratio calculated by the SMAP decoding algorithm.

Another significant patent is the "System and method for one-pass blind transport format detection." This invention is designed for use in a CDMA receiver equipped with a Viterbi decoder. It outlines a system and method for performing one-pass blind transport format detection (BTFD) concerning a received frame. The system includes a traceback circuit that executes a zero state BTFD traceback function, generating hard decision bits, and a BTFD point selection circuit that utilizes these bits to determine the location of a BTFD point within the frame.
