Design and Implementation of Error Detection and Correction in Bit-Swapping LFSR

Abstract

In modern digital communication systems, ensuring data integrity during transmission and storage is a major challenge due to noise, interference, and hardware faults. This project presents the design and implementation of an Error Detection and Correction (EDC) technique using a Bit-Swapping Linear Feedback Shift Register (BS-LFSR) architecture. The BS-LFSR improves upon conventional LFSR structures by introducing controlled bit-swapping operations that enhance fault tolerance and reduce the correlation between error patterns. The proposed system efficiently detects and corrects single-bit and burst errors with minimal hardware overhead. Simulation and synthesis results demonstrate that the BS-LFSR-based EDC mechanism achieves high-speed operation, low power consumption, and improved reliability compared to traditional parity and Hamming code approaches. This makes it a suitable choice for applications in digital communication, memory systems, and error-resilient computing hardware.
