Coding gain refers to the improvement in signal-to-noise ratio (SNR) achieved by using error correction codes in digital communication systems. It quantifies the effectiveness of a coding scheme in reducing the error rate compared to an uncoded system at the same SNR level.

Signal-to-Noise Ratio (SNR) is a measure used to compare the level of a desired signal to the level of background noise, often expressed in decibels. A higher SNR indicates a clearer and more distinguishable signal, which is crucial for effective communication and data processing in various fields such as telecommunications and audio engineering.

Error Correction Codes are algorithms used in digital communications and storage systems to detect and correct errors without requiring retransmission. These codes enhance data integrity and reliability by adding redundancy, allowing the original data to be reconstructed even in the presence of errors.

Error rate is a measure of the frequency of errors in a process or system, often expressed as a percentage or ratio. It is crucial for evaluating the performance and reliability of models, especially in fields like machine learning and quality control, where minimizing errors is essential for accuracy and efficiency.
