Design and Implementation of Convolution Coding Technique in Industrial Automation

In industries, the usage of wireless sensors has been increased tremendously due to various advantages like maintenance, convenient installation, and cable cost reduction. However, the transmission of signals over a wireless channel in a harsh industrial environment is vulnerable to interference of noise resulting in the introduction of errors. This leads to the corruption of data which may result in incorrect feedback that may lead to safety-related problems or economic loss. Thus, in order to reduce the errors, forward error correction codes (FEC) can be used to improve the reliability of the signal transmission. In this paper, the implementation of convolution coding technique in an industrial environment is presented, and the performance has been evaluated in MATLAB/Simulink by comparing bit error rate (BER) with signal-to-noise ratio (SNR).
