Yaoyu Tao is a prominent inventor based in Stanford, CA. He has made significant contributions to the field of low-density parity-check (LDPC) decoding. With a total of 2 patents, his work focuses on enhancing error correction methods in communication systems.

Latest Patents

Yaoyu Tao's latest patents include an innovative LDPC post-processor architecture and method for low error floor conditions. This post-processing circuitry for LDPC decoding features a check node processor that processes shifted log-likelihood ratio (LLR) values. It also includes hard decision decoder circuitry that receives processed LLR information and performs parity checks on this information. The post-processing control circuitry is responsible for updating LLR information in the check node processor. The collaboration between the check node processor, hard decision decoder, and control circuitry allows for the identification of check nodes with unsatisfied parity checks after an iteration cycle. Additionally, it identifies neighborhood variable nodes connected to these unsatisfied check nodes and modifies messages from neighborhood variable nodes to satisfied check nodes as needed to resolve decoding errors. The neighborhood identification circuitry plays a crucial role in determining which variable nodes are connected to unsatisfied check nodes that have failed a parity check.
