Analyzing the Impact of Doppler Shift on COFDM Video Quality

Doppler shift noticeably 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 errors in the received video signal, leading to noticeable impairment in visual quality.

  • The magnitude of Doppler shift effect on COFDM video quality varies on factors such as the speed of motion, the range between the transmitter and receiver, and the channel width of the transmitted signal.
