摘要

In this article a method to increase the signal to noise ratio (SNR) of an impulse-radio ultra-wideband receiver system is investigated. It uses a comb filter to increase the SNR also in case of multipath propagation, narrowband interference and multiple users or sensors, with the advantage that pulse position modulation with energy detection can be used. In theory 10·log(N) dB can be achieved, where N is the number of impulses summed up. Simulations with physical hardware components are discussed and a hardware implementation for the frequency range 3.1 - 10.6 GHz is presented.
