Abstract:
A method for performing frequency correction in a wireless terminal comprising:receiving an Rx RF information signal; down converting the Rx RF information signal based upon a local oscillation to produce an Rx baseband signal; determining an Rx frequency error of the Rx baseband signal; based upon the Rx frequency error, determining an Rx frequency offset command and a Tx frequency offset command; based upon the Rx frequency offset command, phase rotating complex symbols of the Rx baseband signal to frequency correct the Rx baseband signal; based upon the Tx frequency offset command, phase rotating complex symbols of a Tx baseband signal to frequency correct the Tx baseband signal; and up converting the Tx baseband signal based upon the local oscillation to produce a Tx RF information signal.
