«LETI» Unveils Codes to Strengthen Russia’s Telecom Industry
Scientists at Saint Petersburg Electrotechnical University “LETI” have developed a Russian class of error-correcting codes designed to improve the reliability of data transmission over communication channels with high levels of interference.
Data transmission speed is one of the key performance indicators in modern telecommunications. But the ability of a network to preserve data integrity under real-world electromagnetic interference is even more important. Noise and interference are unavoidable when data travels over wires or radio waves, making error correction critical to system reliability. Developing proprietary algorithms for this task is a key element of Russia’s technological sovereignty. The work by LETI scientists provides a practical example: they have developed a new Russian class of error-correcting codes that outperforms existing foreign standards in efficiency.
Invisible Shield for Data
The modern world relies on huge numbers of devices, from routers and switches to fiber-optic modems, that transmit vast amounts of data. As information moves over wires and radio waves, noise and interference can introduce errors. Coding theory addresses this problem by making information transfer, storage and processing faster and more resilient to inaccuracies: it detects distortions and corrects them in real time.
Algebraic constructions used in error-correcting coding theory to protect information from transmission errors, including Bose-Chaudhuri-Hocquenghem (BCH) codes and binary Goppa codes developed in the 20th century, are widely used around the world and remain industry standards. Yet they are complex to implement and less efficient. Meanwhile, Russia is seeking technological sovereignty, making it important to develop a new domestic class of error-correcting codes for data transmitted over noisy channels.
High-interference communication channels are a harsh reality, from noisy industrial environments to deep space. Error-correcting codes act as an intelligent mathematical filter that reconstructs corrupted data packets. The LETI development reduces information transmission errors by 48%, while its frame-error correction efficiency exceeds that of existing foreign standards by 37.5%. This is more than an incremental improvement. It represents a qualitative leap in coding theory, the fundamental language underlying modern telecommunications.
From Taiga to Orbit: Impact on People and Business
For ordinary users, the technology could mean stable mobile connectivity in places where connections previously dropped out completely, including remote settlements, federal highways and factory floors. Operators would no longer have to simply increase network capacity or build new towers to push signals through electromagnetic noise. LETI’s algorithms could provide the best possible quality using existing infrastructure. Fewer failures in digital services and security systems would be an added benefit for users.
For businesses and government agencies, this means more reliable operation of the industrial Internet of Things (IoT), transportation management systems and critical infrastructure. A telemetry transmission failure is unacceptable in these environments, and the new Russian code provides an added layer of protection against such incidents.
Foundation for Sovereignty
Russia is moving from simply replicating foreign technologies to building its own, unique foundation. The LETI development fits into the broader evolution of the country’s telecom industry. In 2024, for example, Roselectronics unveiled reference synchronization sources for digital networks and a 6,000-kilometer beyond-line-of-sight communications technology. In 2025, Skoltech announced the development of generalized LDPC codes for 5G Advanced and 6G networks. Russia is building a complete technology chain, from electronic components and synchronization to fundamental signal-processing algorithms. That is technological sovereignty in practice.
The 6G Race
The global telecom industry is approaching the 6G era, where the focus will be not only on higher speeds but also on ultra-high reliability with minimal latency. Russian error-correction algorithms are precisely the kind of technology that can help the country’s networks meet the demanding requirements of future communications. These algorithms are likely to be particularly valuable for specialized communications and facilities operating in extreme conditions, where conventional methods are ineffective.
LETI’s codes provide a fundamental technology base. These kinds of “invisible” algorithms could help keep Russia’s next-generation networks running reliably over the next three to five years. Integrating Russian algorithms into telecommunications equipment will become a benchmark for quality.
