Abstract
Methods and systems for providing a low-rate data signal. Received input data bits are Manchester modulated onto successive multicarrier symbols in the time domain. Each multicarrier symbol includes orthogonal sub-carrier and a null sub-carrier. A stored waveform can be retrieved to code the sub-carriers. The successive multicarrier symbols are up-converted to a carrier frequency to provide the low-rate data signal, and the low-rate data signal is transmitted.
