1. A digital signal processing system for processing one or more signals, comprising:

  • a first antenna to detect a first signal and to generate a first output signal;

    a second antenna to detect a second signal and to generate a second output signal; and

    a configurable matrix to process at least one of the first and second output signals, the matrix comprising;

    a first amplifier having a first input and a first output, wherein the first input of the first amplifier is selectively coupled to the first antenna;

    a second amplifier having a second input and a second output;

    a switch having a first position coupling the first output of the first amplifier to the second input of the second amplifier, and a second position coupling the second input of the second amplifier to the second antenna;

    a first analog-to-digital converter (ADC) coupled to the first output of the first amplifier; and

    a second ADC coupled to the second output of the second amplifier.
