Abstract
The present invention is a technique of estimating the time and frequency response of at least one desired signal received by at least one antenna. The invention is an update formula for the time-invariant channel responses for multiple transmitting devices, called “Doppler channels”, that model the time-varying channel between each of the transmitting devices and each receiving device. Through use of the update formula, the time-varying channels of the multiple transmitting devices can be better tracked than with prior inventions.
