ABSTRACT:
The use of delay modulation (or "Miller") phase coding to encode transmitted data is disclosed in a multinodal, peer network communication system. The use of delay modulation provides bandwidth compression and reduces the direct current (dc) voltage component of transmitted data. In addition, the delay modulation provides a unipolar communication in which the transmitted waveform contains both data and synchronization information and error detection capabilities.
