The Convolutional Encoder and Viterbi Decoder are integral components of modern digital communication systems, specifically designed to enhance error correction capabilities. This setup is aimed at achieving superior Bit Error Rates (BER) with sustained Signal-to-Noise Ratios (SNRs), leveraging forward error correction mechanisms. The Convolutional Encoder established here operates with a configuration of (3, 1, 4), optimally structuring data for robust transmission by applying a series of generator polynomials. On the decoding end, the Viterbi algorithm is employed, a maximum likelihood convolutional decoder known for its efficacy in decoding convolutional codes. The integration of these components into wireless communication systems affords improved reliability and performance, especially crucial in maintaining data integrity over unstable or noisy communication channels. This solution is highly adaptable, supporting various polynomial configurations and customization needs per customer requirements. Such technology serves wireless applications that demand efficient correction and recovery of transmitted data, and it is suitable for systems where minimal intervention is desired while maintaining high data integrity. This systematic approach integrates support for complex encryption methods, allowing secure and reliable data transfer across multiple communication protocols.
