摘要: Wireless spread spectrum multiple access (SSMA) using time hopping and block waveform encoded (M-ary) pulse position modulated (PPM) signals is analyzed. For different M-ary PPM signal designs, the multiple-access performance in free-space propagation renditions analyzed terms of number users supported by system for a given bit error rate, signal-to-noise ratio, transmission set. The processing gain simultaneous are described parameters. Tradeoffs between receiver complexity discussed. Upper bounds on both maximum total combined rate investigated. This analysis applied to ultrawideband impulse radio modulation. In this modulation, communications waveforms practically realized subnanosecond technology. A numerical example that shows modulation theoretically able provide with capacity hundreds megabits per second at rates range 10/sup -4/ -7/ receivers moderate complexity.
