Method and system for processing a signal

摘要

Method and receiver for processing a signal in a wireless communication system in which the signal comprises a sequence of chips. The signal is receive data at least one rake finger and sampled. There is a time spacing t1 between successive samples less than the time spacing tc between successive chips in the signal. Channel conditions on the channel are estimated and based on estimated channel conditions by the following steps: monitoring timing of the signal on one of the at least one rake finger to determine a time difference between the timing of the signal on the one of the at least one rake finger and the timing of the generation of the samples, the determined time difference being a multiple of t2, where t2

1. A method of processing a signal in a wireless communication system, the signal comprising a sequence of chips, the method comprising:
receiving the signal at a set of rake fingers via a channel; identifying one of said set of rake fingers receiving a greatest signal power; sampling the received signal to generate samples of the signal, wherein there is a time spacing of integer t1 between successive samples which is less than a time spacing of integer tc between successive chips in the signal; estimating channel conditions on the channel; and based on the estimated channel conditions, selectively performing the steps of:
monitoring a timing of the signal on said identified rake finger to determine a time difference between the timing of the signal on said identified rake finger and the timing of the generation of the samples with spacing t1, the determined time difference being a multiple of an integer t2, where t2 is less than t1; andusing the determined time difference to align the timing of the generation of the samples with the timing of the signal on said identified rake finger to within a timing range of integer t2.
