Latest Patents

Chi-Nong Hsieh holds a patent for a "Decoding system for LDPC code concatenated with 4QAM-NR code." This innovative decoding system is designed for use in a Digital Terrestrial Multimedia Broadcasting (DTMB) system. It features a two-stage decoding process where an NR decoder first performs a 4QAM-NR decoding to obtain hard decision information. This information, along with corresponding soft symbol and channel state information, is then processed by a log-likelihood ratio (LLR) device. The LLR device computes a log-likelihood ratio after an adder adds a correction term associated with the hard decision information. Finally, an LDPC decoder receives the LLR for decoding, enhancing the reliability of data transmission.
