Abstract
A communication system includes a transmitter configured to pulse shape a GHM signal to confine the frequency spectrum of the GHM signal within a predefined frequency range. A receiver is also included that receives the transmitted GHM signal. The receiver includes a processor for maximizing the GHM signal to noise ratio and minimizing the bit error rate. The GHM signals are also synchronized to establish a relative time for correct interpretation of bit positions.
