Analyzing the Impact of Doppler Shift on COFDM Video Quality

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

  • The magnitude of Doppler shift influence on COFDM video quality relies on factors such as the rate of motion, the distance between the transmitter and receiver, and the bandwidth of the transmitted signal.
