Claim Text:
1. A method in a mobile terminal of positioning a spurious signal for reducing an impact of the spurious signal on a received Orthogonal Frequency Division Multiplexing (OFDM) signal, the method comprising: determining, by controller circuitry operationally coupled to a first oscillator, a frequency of the spurious signal, wherein the spurious signal originates from a frequency signal of the first oscillator; determining a frequency for a sub-carrier of the OFDM signal; determining a frequency difference between the frequency of the sub-carrier and the frequency of the spurious signal; adjusting the frequency of the first oscillator to decrease the frequency difference; and adjusting, by the controller circuitry that is also operationally coupled to a second oscillator, a parameter related to a frequency of the second oscillator, wherein the parameter includes a control parameter for determining the frequency of the second oscillator.
