| 摘要 |
The present invention relates to a receiver (1) for receiving a spread spectrum modulated signal, comprising at least sampling means (1.1) for forming samples of a received signal, at least one reference code block (1.4) for generating at least first and second reference codes, and a correlation block (1.3). Said correlation block (1.3) comprises means (1.32, 1.33) for forming first and second reference code parts from at least one reference code, means (1.31) for forming a sample string from samples taken of a received signal, and correlation means (1.34) for correlating the first reference code part with the sample string to form first correlation part results, and for correlating the second reference code part with the sample string to form second correlation part results, wherein said correlations are arranged to be performed at different times and by using the same sample string. The invention also relates to an electronic device comprising a receiver, a module to be used in connection with a receiver, and a system comprising a transmitter for transmitting a spread spectrum modulated signal and a receiver for receiving the transmitted signal. Furthermore, the invention relates to a method and a computer software product.
