Abstract

The present invention in one embodiment provides for a propagated signal of (1) a time period divided into a group of time slots each having a unique phase/time position; and (2) multiple pulses distributed among the time slots encoding a data element by such unique phase/time position.

Claims

1. A propagated signal, comprising:

a time period divided into a group of time slots each having a unique phase/time position; and

multiple pulses distributed among said time slots encoding a data element by said unique phase/time position.

2. The propagated signal as recited in claim 1 wherein said data element is ascertainable by mapping.

3. The propagated signal as recited in claim 1 wherein said time slots in said group are adjacent.

4. The propagated signal as recited in claim 1 wherein said time slots in said group are not adjacent.

5. The propagated signal as recited in claim 1 wherein said time slots have a non-uniform spacing.

6. The propagated signal as recited in claim 1 wherein said data element is at least fifteen bits long.

7. The propagated signal as recited in claim 1 wherein said data element is selected from the group consisting of:

a header;

an error detection message;

a synchronization element; and

a data message.

8. The propagated signal as recited in claim 1 further comprising a plurality of said time periods.

9. The propagated signal as recited in claim 8 wherein said groups have differing numbers of multiple pulses.

10. The propagated signal as recited in claim 8 wherein said number of time slots vary in said time periods.

11. A method of propagated a signal, comprising:

designating a time period divided into a group of time slots each having a unique phase/time position; and

distributing multiple pulses among said time slots to encode a data element by said unique phase/time position.

12. The method as recited in claim 11 wherein said data element is ascertainable by mapping.

13. The method as recited in claim 11 wherein said time slots in said group are adjacent.

14. The method as recited in claim 11 wherein said time slots in said group are not adjacent.

15. The method as recited in claim 11 wherein said time slots have a non-uniform spacing.

16. The method as recited in claim 11 wherein said data element is at least fifteen bits long.

17. The method as recited in claim 11 wherein said data element is selected from the group consisting of:

a header;

an error detection message;

a synchronization element; and

a data message.

18. The method as recited in claim 11 further comprising a plurality of said time periods.

19. The method as recited in claim 18 wherein said groups have differing numbers of multiple pulses.

20. The method as recited in claim 18 wherein said number of time slots vary in said time periods.
