Beamforming for impulse-radio UWB communication systems based on complex-valued spatio-temporal neural networks

Abstract

Ultra-wideband (UWB) wireless communications based on impulse radio uses so short pulses that its occupied bandwidth is very large and the density of spectral power is low. Then, UWB has high confidentiality and low interference to other narrowband wireless communications. However, in the situation of multiple access and fixed transmission-speed… (More)
