<p>Systems, apparatuses, and methods for providing timing estimates of received signals are disclosed. In one embodiment, sub-chip timing in spread spectrum signals can be achieved without requiring oversampling in the receiver. A transmitter can adjust the timing of certain transmitted symbols by a fraction of a chip time from an expected time, and send the mistimed symbols to a receiver. The output of the receiver's de-spreading correlator can show different magnitudes for wedge symbols with different timing errors. By setting some symbols early and some late, and by taking the difference between their magnitudes, a transfer function between the result and a timing error can be determined.</p> |
