1. A method of operation of a mobile communication system comprising:
- receiving a base carrier frequency signal for representing the base carrier frequency signal between a mobile device and a cell tower location;
generating a power spectral density from the base carrier frequency signal;
measuring a Rician K factor from the power spectral density;
estimating a line-of-sight frequency and a Doppler frequency based on the power spectral density according to the Rician K factor;
determining a movement for representing direction and speed of the mobile device relative to the cell tower location with a central processor unit based on the line-of-sight frequency, the Doppler frequency, and the Rician K factor; and
activating a handover decision handler based on the cell tower location and the movement.
