Title: The Innovations of Andrei Ovchinnikov

Introduction

Andrei Ovchinnikov is a notable inventor based in St. Petersburg, Russia. He has made significant contributions to the field of electrical engineering, particularly in the area of forward error correction techniques. With a total of nine patents to his name, Ovchinnikov's work has had a substantial impact on data transmission technologies.

Latest Patents

Among his latest patents, one focuses on techniques to perform forward error correction for an electrical backplane. This innovation involves receiving data from a physical coding sublayer (PCS) of a physical layer, which comprises a BASE-R physical layer. The data is utilized to generate a forward error correction (FEC) block that includes a shortened cyclic code with 32 rows of bits. This FEC block consists of payload bits generated from the PCS output and additional bits for transcoding overhead. Furthermore, the FEC block incorporates 32 parity bits at its end and is scrambled using a pseudo-noise sequence before being sent to a physical medium attachment (PMA) sublayer.

Another patent by Ovchinnikov also describes techniques for forward error correction for an electrical backplane. This includes FEC circuitry designed to perform forward error correction, along with physical coding sublayer circuitry and PMA circuitry. The FEC circuitry provides various primitives, including a FEC_UNITDATA.request primitive, a FEC_UNITDATA.signal primitive, and a FEC_UNITDATA.indication primitive. The FEC sublayer features an encoder equipped with a reverse gearbox and a pseudo-noise generator.
