Analyzing the Impact of Doppler Shift on COFDM Video Quality

Doppler shift significantly impacts the quality of video transmitted using Orthogonal Frequency-Division Multiplexing (COFDM). As a signal travels through a medium with varying motion, its frequency shifts. This frequency modulation can introduce artifacts in the received video signal, leading to noticeable degradation in visual quality.

  • The severity of Doppler shift influence on COFDM video quality depends on factors such as the velocity of motion, the distance between the transmitter and receiver, and the frequency range of the transmitted signal.
