Apparatus and method for data rate multiplication

An improvement in an apparatus for pulse position modulating signals comprising means for generating abrupt time spaced phase changes in a carrier frequency, the phase changes having a very short duration to mark the presence of digital ones only.

An improvement in an apparatus for pulse position modulating signals comprising decoding means employing gating periods to separate the pulse position modulated channels and rejecting all signals not within the gate period.

An improvement in an apparatus for pulse position modulating signals comprising means for generating abrupt time spaced phase changes in a carrier frequency, the phase changes having a very short duration to mark the presence of digital ones only and decoding means employing gating periods to separate the pulse position modulated channels and rejecting all signals not within the gate period to realize a single higher data rate channel.

An improvement in a method for pulse position modulating signals which are synchronized to clocked bit periods using a clock comprising:

• generating n signals to mark the presence of digital ones during corresponding n time slots occurring during the same bit period;
• and
• combining the n signals into a single data channel to utilize abrupt phase changes of pulses in a carrier signal at a carrier frequency, the phase changes having a very short duration to mark the presence of digital ones only.
