Optimized Hardware Architecture for Turbo Encoding in Automotive Communication Systems

Abstract

The advancement of intelligent transportation systems and modern automotive electronics has increased the demand for reliable and high-speed communication systems within vehicles. In-vehicle communication networks are responsible for exchanging large volumes of data between sensors, control units, infotainment modules, navigation systems, and autonomous driving platforms. However, automotive communication environments are highly affected by electromagnetic interference, signal attenuation, thermal fluctuations, and transmission noise, which can lead to communication errors and system instability. Conventional error correction methods used in vehicle communication systems often fail to provide sufficient reliability and low-latency performance required for modern automotive applications. To overcome these challenges, the proposed Chip Design for Turbo Encoder Module for In-Vehicle System introduces an optimized VLSI architecture capable of performing high-speed forward error correction encoding with improved communication reliability and reduced power consumption. The proposed turbo encoder module utilizes recursive systematic convolutional encoding techniques and optimized interleaver structures to minimize bit error rates and improve transmission stability in noisy automotive environments. The architecture is implemented using low-power CMOS design methodologies and hardware optimization techniques to achieve compact chip area utilization, faster processing speed, and efficient energy consumption suitable for real-time automotive systems. By integrating FPGA and ASIC implementation strategies, adaptive control circuitry, and parallel processing mechanisms, the proposed system improves data transmission accuracy, communication reliability, and operational efficiency in intelligent transportation systems. The proposed chip design is highly suitable for autonomous vehicles, advanced driver assistance systems, vehicle-to-vehicle communication, automotive infotainment systems, and next-generation embedded automotive electronics requiring secure and reliable high-speed communication.
