DATA COMMUNICATION USING BANDWIDTH MODULATION

摘要

Methods and apparatus to determine a level of inherent jitter for signals from a transmitter and a receiver, and modulate information onto a signal transmitted by the transmitter by using spot jitter (with bandwidth and center frequency modulation) and/or pulse width jitter in a region outside of a data region with inherent jitter to carry communication between systems.

1. A method of pulse width jitter to modulate data onto a signal, comprising:
modulating a pulse width jitter value onto the signal in a buffer area adjacent to a pulse edge of the signal having inherent jitter to generate an output signal, wherein a distance between successive pulse edges of the signal is substantially constant; determining signal characteristics between a transmitter and a receiver to ensure a pulse width jitter magnitude enables resolution of the pulse width jitter value at the receiver, wherein the signal characteristics include range from the transmitter to the receiver; and transmitting the output signal with a transmitter.
