Abstract:

A method is provided for the design of a wide-band high dynamic-range electromagnetic signal receiving system. The method provides for receiving a plurality of analog signals, converting the plurality to a digital replica that can be processed to recover separate high-fidelity replicas of each individual signal in the received plurality. The method also provides increasing the signal dynamic range with a parallel architecture comprising p identical parallel analog-to-digital channels wherein the value of is determined by the ratio of the largest amplitude signal to the minimum detectable signal. Further, it is demonstrated that p is the fundamental limit on the number of parallel channels necessary to linearly process a specified plurality of signals containing a largest signal and a minimum detectable signal.
