1. A system comprising:
a pulse width discriminator operable to couple to a data transmission channel, receive a signal from the transmission channel, and detect the signal at a correct subslot location,
wherein the signal has combined forward and conjugate pulse positions;
a clock operably coupled to the pulse width discriminator;
a demultiplexer operably coupled to the pulse width discriminator and operable to demultiplex the pulse stream in the signal into corresponding sub-slot positions;
a pulse positioner operably coupled to the demultiplexer;
a conjugate counter operably coupled to the pulse positioner and operbly coupled to the clock;
a forward counter operably coupled to the pulse positioner and the clock;
a common slot pulse sorter operably coupled to the conjugate counter and the forward counter;
a data conjugator operably coupled to the conjugate counter;
a data combiner operably coupled to the data conjugator and the forward counter; and
a digital-to-analog converter operably coupled to the data combiner,
wherein the system reconstructs an original signal sample from the forward and conjugate pulse positions.
