Abstract

An approach to reduce the negative impact of multipath signal propagation (interpulse interference) in a wireless communication channel has been proposed. Pulse-interval modulation of chaotic radio pulses allows to increase the time interval between pulses without reducing the average bitrate. The possibility of using this method in ultra-wideband microwave channels with multipath propagation is demonstrated. The noise immunity of the AWGN channel has been studied. An experimental implementation of the method is described.

  • Ultra-Wideband signals, pulse-position modulation
  • pulse-interval modulation
  • chaotic radio pulses
  • detection of chaotic signals

Интервально-импульсная модуляция сверхширокополосных хаотических радиоимпульсов: теория и эксперимент

Предложен подход, который позволяет снизить негативное влияние многолучевого распространения сигнала в беспроводном канале связи, проявляющееся в виде межимпульсной интерференции, за счет использования интервально-импульсной модуляции сверхширокополосных хаотических радиоимпульсов. Интервально-импульсная модуляция дает возможность увеличить временной интервал между импульсами без ущерба для средней скорости передачи данных. Показана целесообразность применения данного метода в сверхширокополосных каналах сверхвысокочастотного диапазона с многолучевым распространением. Исследована помехоустойчивость метода в канале с белым шумом. Описана экспериментальная реализация метода.
