Title: Brian K Gutcher: Innovator in Viterbi Algorithm Technologies

Introduction

Brian K Gutcher is a notable inventor based in Loveland, Colorado. He has made significant contributions to the field of digital signal processing, particularly in the development of methods and circuits for Viterbi algorithm decoders. With a total of 4 patents, Gutcher's work has advanced the reliability and efficiency of data decoding processes.

Latest Patents

Gutcher's latest patents include innovative methods and circuits that comprise a reliability measurement unit (RMU) for generating log-likelihood ratio (LLR) values. These values correspond to 1T for use in a soft output Viterbi algorithm (SOVA) decoder. The RMU operates with an nT clock signal, where 1T signals generated by an add, compare, select circuit (ACS) of the SOVA produce 1T decision data. Additionally, a path equivalency detector generates 1T path equivalency information for 1T SOVA decoding, applying the 1T data to the RMU operating with an nT clock frequency. This innovative approach allows the nT RMU to receive multiple 1T inputs on each nT clock signal pulse, generating 1T LLR information for the SOVA decoder.
