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 varying motion, its frequency modifies. This frequency drift can introduce artifacts in the received video signal, leading to noticeable reduction in visual quality.

• The severity of Doppler shift influence on COFDM video quality relies on factors such as the velocity of motion, the distance between the transmitter and receiver, and the frequency range of the transmitted signal.
• Approaches such as Doppler compensation and adaptive modulation can be employed to mitigate the negative impacts of Doppler shift on COFDM video quality.

Further analysis is ongoingly conducted to develop more efficient methods for managing the impact of Doppler shift on COFDM video transmission.
