SYSTEM AND METHOD FOR NOTCHED SPECTRUM MODULATION OF RADIO FREQUENCY CARRIER WAVES

摘要

Pulse modulation is used in many forms and generally consists of a pulse of radio energy, that can be as simple as On - Off Keying (OOK) to more complex systems like Pulse Position Modulation (PPM) and even more advanced systems. In this application a system and method of adding complexity to the transmission system known as pulse modulation by placing one or more notches in the radio pulse spectrum at the transmitter to indicate a combination of bits or symbols is disclosed.
