Title: Andrey Arkad'evich Shevchenko: Innovator in Data Transmission Technologies
Introduction
Andrey Arkad'evich Shevchenko is a notable inventor based in Nizhniy Novgorod, Russia. He has made significant contributions to the field of data transmission, particularly through his innovative methods that enhance communication efficiency. His work is characterized by a focus on hybrid automatic repeat request (H-ARQ) systems, which are crucial for reliable data transmission.
Latest Patents
Shevchenko holds a patent for a method of hybrid automatic repeat request implementation for data transmission with multilevel coding. This method efficiently combines received signals from multiple H-ARQ block transmission attempts encoded by the Multi-Level Coding approach with an uncoded subset of information bits. The innovation provides full error correction gains of the H-ARQ scheme while reducing decoder computational complexity. The advantages of this method are achieved through the calculation of likelihood ratio metrics and the combination of at least two different data block transmission attempts for both encoded and uncoded bits. Additionally, the calculation of likelihood ratio metrics for uncoded bits considers the results of decoding the encoded bits, leading to improved receiver decisions based on combined likelihood ratio metrics.
Career Highlights
Shevchenko is currently associated with Limited Liability Company “Radio Gigabit,” where he continues to develop and refine his innovative approaches to data transmission. His work has been instrumental in advancing the capabilities of communication technologies, making them more efficient and reliable.
