Abstract
A communication device has a processing unit, a transmit circuit, and an antenna. The processing unit generates a carrier signal and modifies the carrier signal based on a notch modulation procedure having notch delay and a notch width. The notch width is selected based on a desired modulation index. The resulting modulation signal is provided to the transmit circuit, which generates a wireless data signal that is transmitted by the antenna.
