ABSTRACT:
Systems and method for receiving information through narrowband communication channels are provided. The systems and method involve a satellite-based system for receiving a signal, including a receiver filter. The receiver 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.
