<p>A method of transmitting 'biphase' encoded digital signals comprised of the steps of receiving one of a multiplicity of input data bits, wherein each data bit is characterized by a temporal data bit length (12), a temporal bit center (T3) and a temporal state indicative of a logical 1 or 0, and generating an encoded digital baseband signal characterized by a temporal state indicate of a logical state therein the encoded digital baseband signal changes its temporal state according to whether the one input data bit changes its temporal state at a time prior to (T1 or 6) or after (T2 or 7) the temporal bit center (T3). A single sideband with this coding is generated independently by digital synthesis. Detection of the single sideband does not require re-insertion of the carrier.</p> |
