Title: Deyuan Chang: Innovator in Multidimensional Coding Technologies
Introduction
Deyuan Chang is a prominent inventor based in Shenzhen, China. He has made significant contributions to the field of telecommunications and coding technologies. With a total of six patents to his name, Chang is recognized for his innovative approaches to data encoding and decoding.
Latest Patents
One of Deyuan Chang's latest patents is the "Multidimensional Multilevel Coding Encoder and Decoder." This invention involves a multidimensional multilevel coding (MLC) encoder that includes a soft forward error correction (FEC) encoder. The encoder generates soft FEC encoded bits from first bits, while a redundancy generator creates redundant bits from a subset of these encoded bits. Additionally, a hard FEC encoder processes second bits to produce hard FEC encoded bits. The combination of these elements forms labels that map to various constellation points. The MLC decoder, on the other hand, consists of a redundancy decoder, a soft FEC decoder, and a hard FEC decoder, which work together to decode the received bits effectively.
Another notable patent is the "Method for Implementing Turbo Equalization Compensation, Turbo Equalizer and System." This invention outlines a method where an equalizer divides a first data block into multiple segments, with overlapping bits between adjacent segments. It performs recursive processing on each segment and merges them to create a second data block. The system then conducts iterative decoding to produce a third data block, ensuring efficient data processing.
