ABSTRACT:
A wireless communication terminal includes a crystal oscillator, a transceiver and circuitry. The crystal oscillator belongs to a specified type of crystal oscillators in which a dependence of an output frequency as a function of temperature has one or more parameters that vary among the crystal oscillators belonging to the specified type. The transceiver is arranged to perform signal processing operations to a communication signal using the output frequency of the crystal oscillator. The circuitry is arranged to determine a characteristic of the output frequency of the crystal oscillator at one or more operating temperatures, to compute the one or more parameters for the crystal oscillator based on the determined characteristic and the operating temperatures, and to correct a frequency error in the output frequency of the crystal oscillator using the dependence and the computed parameters.
