Abstract:
A method of accepting a sample of an input signal to be used to calculate parameters for a predistortion circuit in an integrated circuit is disclosed. The method comprises accumulating data associated with an input signal over a period of time; detecting the sample of the input signal at a predetermined time; comparing the sample of the input signal to the accumulated data; and determining whether the sample of the input signal is acceptable to be used to calculate parameters for the predistortion circuit. A circuit for accepting a sample of an input signal to be used to calculate parameters for a predistortion circuit in an integrated circuit is also disclosed.
