Abstract

Systems and methods for providing modulation on demand in a narrowband communication system are provided. Modulation on demand is accomplished by a novel modulation scheme that achieves high bandwidth efficiency for various channel conditions and modulation parameters. Such modulation parameters may include the carrier frequency, the number of RF cycles per bit, and the number of samples per RF cycle, among others. A communication system employing the modulation on demand scheme transmits a message signal via one or more look-up tables storing samples representing the modulated message signal.
