A New Modulation Method for Digital Communication

We present the design of a transmitter and a receiver for digital communication system that uses function modulation (fm) method. The design covers both orthogonal and non-orthogonal analytic functions. The design is based on the concept of software radio on a general purpose Digital Signal Processor (DSP). A numerical method for generating the waveforms required for the fm system is presented. Experimental results on real environment, demonstrating the feasibility of the concept, are also discussed.
