Channel impairment in signals transmission: Noise, fading and distortion etc. that result in transmission quality degradations.
time variation of transmission channel due to changes of envirenment and the effect of Doppler to transsmited signal

Channel estimation in Orthogonal Frequency Division Multiplexing (OFDM) refers to the process of estimating the characteristics of the communication channel through which the OFDM signals are transmitted. This estimation is crucial for accurately recovering the transmitted data, as it allows the receiver to compensate for the effects of multipath fading and frequency-selective fading inherent in wireless channels. Techniques such as pilot symbols and training sequences are often used to aid in the estimation process. Accurate channel estimation helps improve the overall performance and reliability of the OFDM system.

Flat fading, or nonselective fading, is that type of fading in which all frequency components of the received signal fluctuate in the same proportions simultaneously. Selective fading affects unequally the different spectral components of a radio signal.
