METHOD AND APPARATUS FOR COMBINING PHASE SHIFT KEYING AND PULSE POSITION MODULATION

摘要

The present invention provides for a propagated signal modulated by phase and time shift keying and a method of using the same. In one embodiment the propagated signal includes: 1 a period of time spanned by a pulse, the period of time divided into a group of time slots, each of the time slots having a unique phase/time position and 2 the pulse encoding a data element by the phase/time position.
