Abstract
A method of synchronizing to a pseudo random sequence, which can be generated by a linear feedback shift register having k stages and p intermediate taps, where k and p are positive integers and k>p, and a synchronization arrangement for carrying out the method are described. A received symbol sequence is supplied to a k-stage shift register with p intermediate taps in positions corresponding to the p taps of the linear feedback shift register. A respective correlation signal is recursively added at an input for the received symbol sequence and at each intermediate tap. Each correlation signal is produced by correlating at least two signals from said input, intermediate taps, and output other than the signal to which the respective correlation signal is added. The invention is particularly applicable to pilot synchronization in CDMA terminals.
