Abstract
A method and apparatus for modulating a pulse signal with a bit stream is disclosed. The pulse signal is modulated by selectively inverting and delaying signal pulses within the pulse signal responsive to bits within the bit stream.
Claims31
An apparatus for modulating a bit stream onto a pulse signal for transmission, the apparatus comprising:
- a pulse generator that generates a selectively delayed and inverted signal pulse responsive to a phase signal and a delay signal;
- a phase controller coupled to the pulse generator, the phase controller configured to generate the phase signal responsive to a first data bit of the bit stream;
- and
- a delay controller coupled to the pulse generator, the delay controller configured to generate the delay signal responsive to a second data bit of the bit stream.
A method for modulating a bit stream onto a pulse signal for transmission, the method comprising the steps of:
- selectively inverting a signal pulse responsive to a first bit of the bit stream;
- and
- selectively delaying the signal pulse responsive to a second bit of the bit stream.
A method for modulating a bit stream onto a pulse signal for transmission, the method comprising the steps of:
- receiving a bit stream having a first and a second bit;
- and
- selectively inverting and delaying a signal pulse responsive to the first and second bits of the bit stream.
A system for modulating a bit stream onto a pulse signal for transmission, the system comprising:
- means for selectively inverting a signal pulse responsive to a first bit of the bit stream;
- and
- means for selectively delaying the signal pulse responsive to a second bit of the bit stream.
A computer readable carrier including software that is configured to control a computer to implement a modulation method embodied in a computer readable medium, the modulation method including the steps of:
- selectively inverting a signal pulse responsive to a first bit of the bit stream;
- and
- selectively delaying the signal pulse responsive to a second bit of the bit stream.
