Abstract
A method to receive channels in an undersampled broadband receiver is provided. The method includes converting received radio frequency signals to downshifted-sampled-digital signals at an analog-to-digital converter in a sampling system, outputting the downshifted-sampled-digital signals to a digital system for digital processing, and determining if the unique identifying code associated with a desired channel is detectable. Each channel in the radio frequency signal has an assigned unique identifying code. When the unique identifying code is detectable, the method includes detecting the unique identifying code associated with the desired channel. When the unique identifying code is undetectable, the method includes outputting control signals from the digital system to tune an adjustable sample clock in the sampling system and tuning the adjustable sample clock based on the output control signals.
