Patent ID: 7761077

Claim:
A diversity receiver for receiving a desired content carried by a radio signal on a radio channel, said diversity receiver comprising: a first receiving branch having associated thereto a first antenna element for receiving a first signal; at least a second receiving branch having associated thereto a second antenna element for receiving a second signal; first means for obtaining, from the first signal on the first receiving branch and the second signal on the second receiving branch, a third signal representing an estimation of a spatial derivative of at least one receiving channel parameter; second means for processing the third signal to obtain a, fourth signal; third means for processing the first signal, as received by the first receiving branch, to obtain a fifth signal; and fourth means for combining the fourth signal and the fifth signal to obtain an output signal, said output signal corresponding to the desired content of the radio signal, wherein the third signal is used to cancel or at least reduce signal distortions that occur due to time-variations of the receiving channel, and wherein the first antenna element and the second antenna element are closely spaced and arranged behind each other in a direction of motion of the diversity receiver.
