Abstract:
At least one embodiment of the invention provides an automated frequency offset compensation method, system, and apparatus that improves throughput between one or more wireless communication devices by compensating for frequency offsets caused by a Doppler effect. In particular, one implementation estimates the frequency offset and uses this to compensate the carrier signal power to interference power ratio (C/I) when the transmitting and receiving devices are moving relative to each other such that a Doppler effect creates a frequency offset in the perceived frequency of the received carrier signal.
