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 ( 300, 301 ) that are obtained by spreading at least a first and second data symbol stream with a respective first ( 302 ) and second code, with said first code ( 302 ) to obtain at least two portions ( 303 - 1, 303 - 2 ) of a Cross-Correlation Function CCF ( 303 ), and combining said at least two portions ( 303 - 1, 303 - 2 ) of said CCF ( 303 ) to obtain a combined CCF portion from which a first delay of said first spread data symbol stream is determined, wherein said first code ( 302 ) and said second code are composed of chips and wherein the number of chips of said first code ( 302 ) 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.
