Title: Innovations of Chris Heegard
Introduction
Chris Heegard is a notable inventor based in Ithaca, NY (US). He has made significant contributions to the field of coding schemes, particularly in the area of concatenated trellis coded modulation and linear block codes. With a total of 10 patents to his name, Heegard's work has had a substantial impact on data encoding techniques.
Latest Patents
One of Heegard's latest patents involves a concatenated trellis coded modulation and linear block encoding scheme. This innovative approach splits data into two streams, where one stream is both linear block encoded and trellis encoded, while the other may remain uncoded or use a weaker linear block code. The coding scheme necessitates a specialized decoder that first decodes the trellis encoded data, subsequently using that information to decode the non-trellis encoded data. By selecting the relative strengths of the two linear block encoders, Heegard maximizes coding gain and efficiency.
Career Highlights
Throughout his career, Chris Heegard has worked with prominent companies, including General Instrument Corporation of Delaware and General Instrument Corporation. His expertise in coding schemes has positioned him as a valuable asset in the field of data encoding.
Collaborations
Heegard has collaborated with notable colleagues such as Woo H Paik and Scott A Lery. Their combined efforts have contributed to advancements in coding technologies.
Conclusion
Chris Heegard's innovative work in concatenated trellis coded modulation and linear block codes showcases his significant contributions to the field of data encoding. His patents and collaborations reflect a commitment to enhancing coding efficiency and effectiveness.
