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.

Abstract translation: 一种方法，包括将具有第一偏移的码与信号相关以产生第一相关结果; 将具有第二偏移的代码与所述信号相关联以产生第二相关结果; 使用所述第一相关结果和所述第二相关结果确定成本函数; 以及根据所述成本函数调整所述第一偏移和所述第二偏移，其中所述成本函数使用所述第一相关结果的第一加权和所述第二相关结果的第二不同加权。
