Apparatus and method to process signals from one or more transmission sources

摘要

A receiver and a method to process signals from one or more transmission sources. The receives includes a front-end having: an input coupling path to route an analog input signal received from one or more transmission sources; an equalizer to generate an equalized signal from the analog input signal; and an ADC to generate a digitized signal from the equalized signal. The method includes routing the analog input signal through an input coupling path; equalizing the analog input signal to generate an equalized signal therefrom; and digitizing the equalized signal to generate a digitized signal therefrom.

1. A receiver comprising a front-end, the front end including:
a plurality of input coupling paths to route a corresponding plurality of analog input signals received from one or more transmission sources; a plurality of low-noise amplifiers (LNAs) to generate a plurality of amplified analog input signals from the plurality of analog input signals, each of the plurality of LNAs coupled to at least one of the plurality of input coupling paths; a plurality of equalizers to generate a plurality of equalized signals from the plurality of amplified analog input signals, each of the plurality of equalizers coupled to at least one of the plurality of input coupling paths and at least one of the plurality of LNAs; a weighted adder coupled to each of the plurality of equalizers, the weighted adder to generate a composite equalized signal from the plurality of equalized signals; an analog to digital converter (ADC) coupled to the weighted adder, the ADC to generate a digitized signal from the composite equalized signal; and a digital signal processor (DSP) coupled to the ADC to receive the digitized signal therefrom, the DSP being adapted to demodulate the digitized signal.
