Provided is a method to process a pulse width coded signal. The method includes digitizing a received pulse width coded signal and transforming the digitized signal to at least one of power domain and absolute value domain. The converting produces a converted signal. The method also includes estimating a signal power of the converted signal in a wide band filter to produce data representative of a first signal having first type signal shape properties and estimating a signal power of the converted signal in a narrow band filter to produce data representative of a second signal having second type signal shape properties. Finally, the first and second type data are compared to produce information representative of pulse width characteristics of the received signal.
