Doppler spread is the range of frequencies over which the received Doppler spectrum is essentially non zero. When a pure sinusoidal of frequency 𝑓𝑐 is transmitted, the received signal spectrum, called the Doppler spectrum, will have components in the range 𝑓𝑐+𝑓𝑑 to 𝑓𝑐−𝑓𝑑, where 𝑓𝑑 is the Doppler shift.
