发明名称 Automatic frequency control by an adaptive filter
摘要 The process of the present invention generates an optimum automatic frequency control signal in an apparatus that has a plurality of adaptive algorithms, each adaptive algorithm having a reference signal with an associated frequency dither. The process starts by comparing the performance of each of the plurality of adaptive algorithms. This difference is input to a comparator where it is compared to zero. This delta signal then modifies the numerically controlled oscillator frequency. After several iterations, the frequency offset is reduced to substantially zero.
