A digital communication system and method is provided for increasing bit-rates while maintaining the reliability of transmitted digital information and avoiding increased power demands. The communication system includes a transmitter that modulates one or more bits onto a carrier signal to generate and transmit a first transmission signal during the first part of a pulse time TB, receives an additional bit, and based on the value of the additional bit, either transmits the first transmission signal again during the second part of the pulse time TB or transmits a second transmission signal during the second part of the pulse time TB. The communication system also includes a receiver that receives a transmission signal, demodulates the transmission signal during the first part of a pulse time TB to determine a value for one or more received bits, accumulates a voltage from the transmission signal during the second part of the pulse time TB to generate an accumulated voltage, measures the accumulated voltage, and assigning either a first value or second value to an additional received bit based on the value of the accumulated voltage.
