Patent Images
1. An electronic equipment, comprising:
- a RAKE receiver for receiving a signal, said receiver including at least one finger having a settable time delay;
a transducer operable to provide a signal indicative of motion of the electronic equipment; and
a delay estimator circuit operative to calculate a duration between fading nulls of a signal received by the RAKE receiver based on the motion signal, wherein the time delay of the at least one finger is set based on the duration between fading nulls.

Abstract
An electronic equipment includes a RAKE receiver that includes at least one finger having a settable delay, a transducer operable to provide a signal indicative of motion of the electronic equipment, and a delay estimator circuit operative to calculate a duration between fading nulls of a received signal based on the motion signal of the electronic equipment. The time delay of the at least one finger is set based on the duration between fading nulls.

21. A non-transitory computer readable storage medium having an executable program stored thereon for setting a time delay for at least one finger of a RAKE receiver in an electronic device, wherein the program instructs a processor to perform the following steps:
-
obtain from a transducer of the electronic device a signal indicative of motion of the electronic device; calculate a duration between fading nulls of a signal received by the RAKE receiver based on the motion signal; and set a time delay of the at least one finger based on the duration between fading nulls.
