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 drift can introduce errors in the received video signal, leading to noticeable impairment in visual quality.
- The magnitude of Doppler shift influence on COFDM video quality relies on factors such as the velocity of motion, the range between the transmitter and receiver, and the channel width of the transmitted signal.
