A system and associated methods that use separate paths to send amplified data. The method expands, or amplifies, the amount of data that can be transmitted over a dedicated bandwidth-limited communications medium by using a first channel for transmitting clock synchronization pulses and transmitting the data as pulse position modulated (PPM) data over a second separate bandwidth-limited communication channel. Data for transmission is encoded by determining if the period of a pulse encroaches into the frame of the subsequent pulse. In response to a determination of encroachment, one or both of the pulses are inverted and time shifted to eliminate the encroachment. In the event that inversion of one or both of the pulses does not eliminate the encroachment, a blank is inserted between the two pulses.
