What is equalization in communications?

Equalization in communications refers to the process of adjusting the received signal to compensate for distortions and impairments that occur during transmission over a medium, such as a wire or wireless channel. It aims to restore the original signal quality by minimizing the effects of factors like multipath fading, interference, and frequency response variations. Equalization techniques can be implemented using analog or digital methods, with various algorithms designed to adaptively adjust the signal based on the channel characteristics. This ensures improved data integrity and overall communication performance.
