Abstract:
A method of generating a signal for fine tuning the tracking of a communication signal in a wireless infrastructure comprising the steps of:combining an early real PN despread pilot symbol signal with a late real PN despread pilot symbol signal to obtain a first difference signal; combining an early imaginary PN despread pilot symbol signal with a late imaginary PN despread pilot symbol signal to obtain a second difference signal; generating an estimated ontime real PN despread pilot symbol signal; multiplying the first difference signal with the estimated ontime real PN despread pilot symbol signal to obtain a first sum signal; generating an estimated ontime imaginary PN despread pilot symbol signal; multiplying the second difference signal with the estimated ontime imaginary PN despread pilot symbol signal to obtain a second sum signal; and adding the first sum signal to the second sum signal to obtain a tracking signal.
