A method for determining a delay of a spread data symbol stream comprises the steps of at least partially correlating a signal, which comprises at least first and second spread data symbol streams () that are obtained by spreading at least a first and second data symbol stream with a respective first () and second code, with said first code () to obtain at least two portions (--) of a Cross-Correlation Function CCF (), and combining said at least two portions (--) of said CCF () to obtain a combined CCF portion from which a first delay of said first spread data symbol stream is determined, wherein said first code () and said second code are composed of chips and wherein the number of chips of said first code () is different from the number of chips of said second code. The invention further relates to a computer program, a computer program product, a device and a system.
