ABSTRACT:
Systems and method for receiving information at very high data rates through narrowband communication channels are provided. The systems and method involve filtering a received signal with a high-precision digital filter and demodulating the filtered signal with a novel return-to-zero, abrupt phase demodulation technique. The digital filter is designed based on fractal modeling of the frequency spectrum of the received signal. The systems and method of the present invention enable data rates exceeding 5 Mbps to be received through frequency channels as narrow as 50 KHz under a variety of channel conditions.
