Abstract
Systems, devices and techniques for wireless communications include receiving a plurality of wireless transmissions over an observation period from a transmitter of a mobile terminal, calculating a plurality of frequency offset values based on the received plurality of wireless transmissions and estimating a speed value based on the plurality frequency offset values. In some implementations, the speed value is determined as a function of a computed frequency offset measurement error. Implementations can be made to include estimating channel characteristics in communication between a base station and the mobile terminal based on the estimated speed and optimizing a property in communications with the mobile terminal based on the estimated channel characteristics. In some implementations, the property can include a modulation scheme or scheduling of transmissions for communications between the base station and the mobile terminal.
