A method, apparatus and system that tracks distorted signals in a digital system is disclosed. The method may include receiving an input signal having a first input value when a distorted signal is input to the digital system and has a second input value when a non-distorted signal is input to the digital system, and outputting a signal having a first output value to indicate that a corresponding output signal from the digital system is distorted and has a second output value to indicate that a corresponding output signal from the digital system is not distorted.

An ultra-wideband (UWB) communications system combines the techniques of a transmitted reference (TR) and a multiple access scheme called delay hopping (DH). Combining these two techniques using UWB signaling using a continuous noise transmitted waveform avoids the synchronization difficulties associated with conventional approaches. This TR technique is combined with the DH multiple access technique to create a UWB communications scheme that has a greater multiple access capacity than does the UWB TR technique by itself.
