Patent ID: 8503507

Claim:
A method of multi-tune implementation incorporation frequency offset correction, comprising: providing a single fixed frequency oscillator electronically connected to a divider and providing an input channel in communication with the divider and an analog-to-digital converter, the input channel having a first bandwidth, the converter having a second bandwidth, the second bandwidth being broader than the first bandwidth, the single fixed frequency oscillator operating at a frequency higher than frequencies inside an entire reception band of the input channel, the divider dividing the frequency of the single fixed frequency oscillator, wherein the divided frequency being used as input for producing sub-bands of frequencies that cover the entire reception band, operating at least two tuners concurrently based on the single fixed frequency oscillator, and using a difference between a measured oscillator frequency of the single fixed frequency oscillator and a required frequency to determine a frequency offset value to correct the measured oscillator frequency at an intermediate frequency to baseband converter, in a feed-forward manner.
