Abstract
In one embodiment, a method comprising sampling by a first sampling unit a first signal received via a first antenna; and sampling by a second sampling unit a second signal received via a second antenna, the sampling of the second signal commencing in synchronization with the sampling of the first signal by the first sampling unit based on an accumulated value, the first and second signal sharing common information.
Claims20
A system, comprising:
- an accumulator;
- a first sampling unit configured to sample a first signal beginning with a first initial sampling point, the first signal having information;
- a second sampling unit configured to sample a second signal having the information, the second sampling unit configured to be synchronized with the first sampling unit at a second initial sampling point that follows the first initial sampling point based on input from the accumulator;
- and
- a delay lock loop configured to drive a sampling rate of the first and second sampling units after the second initial sampling point.

A method, comprising:
- sampling by a first sampling unit a first signal received via a first antenna;
- and
- sampling by a second sampling unit a second signal received via a second antenna, the sampling of the second signal commencing in synchronization with the sampling of the first signal by the first sampling unit based on an accumulated value, the first and second signal sharing common information.
A system, comprising:
- a delay lock loop configured to provide a sampling adjust signal;
- plural antennas;
- a first sampling unit, the first sampling unit configured to sample a first multipath signal received via a first of the plural antennas according to the sampling adjust signal;
- an accumulator configured to store accumulated differences in sampling points associated with the sampling of the first multipath signal;
- and
- a second sampling unit configured to sample a second multipath signal received via a second of the plural antennas, the sampling of the second multipath signal commencing in synchronization with the sampling of the first signal by the first sampling unit based on an accumulated value corresponding to the accumulated differences and the sampling adjust signal.
