Abstract
A system for and method of converting successive bits of digital data into BPSK symbols using one or more BPSK symbol constellations such that orthogonal BPSK constellations are referenced to successive bits of the digital data. The system and method may toggle between referencing first and second orthogonal constellations as successive bits of the digital data are encountered. Alternatively, the system and method may successively rotate by 90° the constellation to be referenced as successive bits of the digital data are encountered. The reversal of the systems and methods described can be used to decode a transmission made by the methods described or specifically to reference a succession of orthogonal BPSK constellations to convert a succession of BPSK symbols to a succession of bits of digital data. Furthermore, a standard quadrature receiver can be used to perform the conversion.
