ABSTRACT:
A method and system for providing a frequency correction for a spread spectrum communication receiver. In the method and system, a frequency offset is determined by processing successive samples of a despread data signal. A correction sequence is generated from this determined offset and combined with a code-spread received signal prior to despreading. A filter may be included in order to reduce noise in the system.
