Title: Innovations of Alvin Lai Lin

Introduction

Alvin Lai Lin is a notable inventor based in Londonderry, GB. He has made significant contributions to the field of technology, particularly in the area of low-density parity check (LDPC) decoders. With a total of 6 patents to his name, his work has had a considerable impact on the industry.

Latest Patents

One of Alvin's latest patents is the Accumulating LDPC (Low Density Parity Check) decoder. This innovative architecture is designed for LDPC codes that operate on a parity check matrix, H, which consists of cyclic shifted identity (CSI) sub-matrices or permuted identity sub-matrices. The entire LDPC matrix is divided into square sub-matrices, where each sub-matrix can be a CSI sub-matrix, a permuted identity sub-matrix, or a null matrix. The iterative decoding process involves updating a posteriori probability (APP) or gamma (γ) values and check edge message (λ) values. This is achieved by processing one or more individual rows within several sub-matrix rows in parallel. The level of parallelism is determined by the designer and is typically an integer divisor of the sub-matrix size.
