Integer cycle event detection using wavelet pass filter system and method
View Patent ↗A system and method to transport high bit-rate data over wired or wireless communication systems using specially modulated radio frequency carrier waves using an integer cycle or impulse modulation detection method where the signal to be demodulated is generally split, delayed, inverted and summed. When such integer cycle or impulse modulation modulated signals are passed through the system, the delayed signal is not the inverse of the non-delayed signal when there is data present. The resultant summed signal does not cancel completely, thus, resulting in a demodulated signal that is present only as long as the data is present in the integer or impulse modulated signal. This nulling effect also results in reducing the interference from other signals thereby improving the signal to noise ratio of the system. Thus the system not only reduces the interference from other channels, but it is a very fast demodulator that has the capability of demodulating the signal on an integer cycle basis.
