Multiple-access with time hopping and block waveform PPM modulation

Abstract

The use of time-hopped block waveform encoding PPM signals sets for multiple access communications is studied. The multiple access performance is analyzed in terms of the number of users supported by the system for a given bit error rate and bit transmission rate. The analysis shows that this technique is potentially able to provide multiple-access communications with a combined transmission capacity of over 500 Megabits per second at bit error rates in the range 10/sup -4/ to 10/sup -8/ using receivers of moderate complexity.
