Title: Yang Yang and Wyner-Ziv Coding Based on TCQ and LDPC Codes.

Introduction

Yang Yang is an inventor associated with College Station, Texas, and the Texas A&M University System. His patent work concerns efficient source coding, combining trellis-coded quantization with low-density parity-check codes.

Latest Patents

Yang Yang’s listed patent, “Wyner-Ziv Coding Based on TCQ and LDPC Codes,” describes an encoder that processes source samples using trellis-coded quantization (TCQ). The TCQ uses polynomials selected to maximize granular gain, while a compression unit applies parity-check matrices from corresponding LDPC codes to bit planes of the quantized output and produces syndromes. The matrices are selected so that compression performance approaches the Slepian-Wolf coding limit.

On the decoder side, the invention uses correlated side information to decode the syndromes and estimate the TCQ output. An estimation unit then combines that estimate with the side information to reconstruct the source samples. Trellis-coded vector quantization is described as an alternative to TCQ. The supplied patent information lists 2 patents, but provides the same patent description twice, so it does not establish details of a second distinct patent.
