Abstract
A communication system is provided which offers increased transmission speed while maintaining a low bit error rate. At the transmitter, a digital input is entered and a microprocessor determines from a particular subset of pulse sequence codes a single sequence of pulse coefficients that corresponds to that particular digital input. The sequence of pulse coefficients are then multiplied by a pulse shape, modulate and transmitted. At the receiver, the modulated pulses are demodulated. The demodulated pulses are then, on a pulse by pulse basis, subtracted from each of the subset of pulse sequences with the absolute values of each pulse for each pulse sequence being summed. A comparator selects a sequence of pulse coefficients corresponding to the lowest summed value of a particular pulse sequence, which is then mapped to a digital signal which is the same digital signal as the digital input.
