Patent ID: 8081585

Claim:
A multi-hop booster system comprising: a network unit communicating with a wireless base transceiver and a user unit communicating between the network unit and a user device, the network unit comprising: an analog-to-digital converter to digitize radio frequency signals from the wireless base transceiver; a polyphase filter for filtering the digitized radio frequency signals from the analog-to-digital converter; a fast fourier transform processor for performing a Fast Fourier Transform (FFT) operation on the filtered, digitized radio frequency signals; a channel selection and multiplexing processor for channelizing and multiplexing the output of the fast fourier transform processor; and a digital-to-analog converter to convert the digitized radio frequency signals into analog output signals on one or more channels; and the user unit comprising, for each of the one or more channels: an analog-to-digital converter to digitize the analog output signals from the network unit; a channel estimator for estimating a selected channel of the one or more channels on which the analog output signals are received; and an equalizer to equalize any time dispersal on the selected channel; and the user unit further comprising: a coherent combiner to combine outputs of the equalizers; a polyphase filter for filtering the combined outputs of the equalizers; a fast fourier transform processor for performing an FFT operation on the filtered, combined outputs of the equalizers; a channel selection and demultiplexing processor for channelizing and demultiplexing the filtered, combined outputs of the equalizers; and an analog-to-digital converter to digitize the filtered, combined outputs of the equalizers to produce a boosted output signal for the user device.
