PROFILE
Tomoya Hagen
Tomoya Hagen developed robust channel coding features for the SpaceTeam/STS1_COBC_SW repository, focusing on enhancing data integrity and transmission reliability in embedded RF communication systems. Over three months, Tomoya implemented Reed-Solomon encoding and decoding, bit scrambling, and a ViterbiCodec-based convolutional coding module, all integrated with C++ and CMake. He introduced a configurable build-time toggle for punctured and non-punctured convolutional coding, supporting flexible deployment and streamlined testing across hardware configurations. The work included comprehensive unit testing and system integration, demonstrating depth in algorithm implementation and build system design while laying a foundation for future performance tuning and error resilience.

Aug 1, 2025August 2025 (SpaceTeam/STS1_COBC_SW) delivered a configurable convolutional coding pathway by introducing a build-time toggle to enable or disable puncturing. This adds flexibility for deployment and testing across hardware configurations while maintaining a unified encoding path. The work included a new non-punctured implementation and a refactor of ViterbiCodec to support both punctured and non-punctured modes, reducing maintenance overhead and enabling dual-mode operation. The changes were implemented through two commits and set the foundation for performance tuning and broader deployment scenarios.
