Patent ID: 8121223

Claim:
An apparatus having an input port and comprising: a first RF filter bank having an input coupled to the input port of the apparatus, said first RF filter bank comprising a plurality of filters; a decision network coupled to an output of said first RF filter bank; plurality of mixer circuits, each of said plurality of mixer circuits adapted to receive a first signal from a respective one of the plurality of filters in said first RF filter bank; plurality of digitally controlled oscillators (DCOs), each of said plurality of DCOs adapted to receive an input signal from said decision network and to provide a second signal to a respective one of said mixers wherein each of said plurality of mixer circuits provides an intermediate frequency (IF) signal at an output port thereof; a second filter bank comprising N filters, said second filter bank coupled to the output port of each of said plurality of mixer circuits such that said second filter bank receives IF signals from the output ports of said plurality of mixer circuits and provides an appropriately filtered signal to said decision network, said second filter bank providing a plurality of output signals.
