Claims28
A wireless communication system, comprising:
- a first wireless module disposed on a front of a vehicle, the first wireless module configured to manage wireless signals in a forward area of the vehicle;
- a second wireless module disposed on a side of the vehicle, the second wireless module configured to manage wireless signals in a side area of the vehicle;
- a third wireless module disposed on a rear of the vehicle, the third wireless module configured to manage wireless signals in a rear area of the vehicle;
- a velocity module configured to indicate velocity information of the vehicle;
- and
- a signal compensation module communicatively coupled to the first wireless module, the second wireless module, the third wireless module, and the velocity module, the signal compensation module configured to determine a Doppler frequency shift compensation component associated with at least one of the wireless signals in the forward area of the vehicle, the wireless signals in the side area of the vehicle, or the wireless signals in the rear area of the vehicle based, at least in part, on a relationship between the velocity information of the vehicle, a nominal frequency for the wireless signals, and the propagation speed of light.

In a wireless communication system, a method for compensating for Doppler frequency shift, comprising:
- managing wireless signals in a forward area of a vehicle;
- managing wireless signals in a side area of the vehicle;
- managing wireless signals in a rear area of the vehicle;
- receiving an indication of velocity information of the vehicle;
- and
- determining a Doppler frequency shift compensation component associated with at least one of the wireless signals in the forward area, the wireless signals in the side area of the vehicle, or the wireless signals in the rear area of the vehicle based, at least in part, on a relationship between the velocity information of the vehicle, a nominal frequency for the wireless signals, and the propagation speed of light.
