Patent ID: 8310387

Claim:
An apparatus for receiving a signal from a frequency multiplexed communication system comprising: a plurality, M, of time-interleaved analog-to-digital converter (ADC) subunits, coupled to receive the signal from the frequency multiplexed communication system at an input and provide a digital representation thereof at an output; and a clock circuit, coupled to provide one or more clock signals to the plurality, M, of time-interleaved ADC subunits, such that at least one of the ADC subunits samples the frequency multiplexed communication signal at a sample clock rate, FS 1 , and such that the M ADC subunits together providing an aggregate sample clock rate, FS, of the frequency multiplexed communication signal, and further such that FS 1 is a predetermined frequency selected to locate a Nyquist frequency of a respective one of the M ADC subunits in one or more guard band regions of the frequency-multiplexed communication system, and such that one or more integer multiples of FS 1 are located in one or more guard band regions of the frequency-multiplexed communication system.
