1. A method comprising:
- correlating a code having a first offset with a signal to produce a first correlation result;
correlating the code having a second offset with the signal to produce a second correlation result;
determining a cost function using the first correlation result and the second correlation result; and
adjusting the first offset and the second offset in dependence upon the cost function,wherein the cost function uses a first weighting for the first correlation result and a second, different weighting for the second correlation result.

Abstract
A method including correlating a code having a first offset with a signal to produce a first correlation result; correlating the code having a second offset with the signal to produce a second correlation result; determining a cost function using the first correlation result and the second correlation result; and adjusting the first offset and the second offset in dependence upon the cost function, wherein the cost function uses a first weighting for the first correlation result and a second, different weighting for the second correlation result.

27. A computer-readable storage medium encoded with instructions that, when executed by a processor, enable the processor to perform any one of the steps of:
-
determining a cost function using a first correlation result, formed by correlation of a code having a first offset with a signal, and a second correlation result, formed by correlation of the code having a second offset with the signal; controlling adjustment of the first offset and the second offset in dependence upon the cost function, wherein the cost function uses a first weighting for the first correlation result and a second, different weighting for the second correlation result.
