channelestimation
Channel estimation is a fundamental process in digital communications that involves determining the characteristics of a communication channel. The channel, which is the medium through which signals are transmitted, can introduce distortions such as attenuation, phase shifts, interference, and noise. Accurate channel estimation is crucial for effective signal recovery at the receiver.
The process typically involves transmitting known pilot signals or training sequences. The receiver knows these sequences
Various algorithms exist for channel estimation, with the choice depending on factors like channel variability, available
