Abstract
Embodiments of the disclosure provide methods, apparatus, and articles allowing two nodes to communicate in a slot-based direct sequencing spreading communication system. Both a preamble sequence and a payload data spreading PN sequence are generated from the Time of Day and a given user code. Generated sequences are synchronized between two communicating nodes to allow slot-based DSSS communication to take place. Generated sequences also change dynamically from slot to slot to provide waveform security.
