Patent abstract
A method of demodulating a frequency hopped waveform is disclosed. The method comprises receiving an analog radio frequency signal, converting the analog signal to a digital pulse signal, and determining the I and Q bits in the digital pulse signal. The method also comprises derotating the Q bits by a ninety (90) degree phase shift. The method further comprises deriving an approximate phase angle for the pulse from the I and derotated Q bits.
