 Equalization (communications)

Equalization in communications refers to a signal processing technique used to counteract the effects of distortion that a signal may experience during transmission over a communication channel. Distortion can arise due to various factors, including interference, multipath propagation, and frequency-selective fading, which can alter the signal's amplitude and phase characteristics as it travels. The primary goal of equalization is to improve the quality and reliability of the received signal by compensating for these distortions.
