摘要: Multiple input multiple output-ultrawide band (MIMO-UWB) systems are experimentally evaluated for underground mine high-speed radio communications. Measurement campaigns using two different antenna configurations have been made in an gold mine. Furthermore, scenarios, which the line of sight (LoS) and non-LoS (NLoS), i.e., taking into account mining machinery effect, distinguished studied separately. In fact, channel is characterized terms coherence bandwidth, path loss, shadowing, correlation, capacity. Results reveal how array configuration affects main parameters suggest that presence substantially both received power time dispersion within should, therefore, be considered when assessing performance in-gallery wireless systems. Moreover, it shown MIMO-UWB takes benefit large spreading bandwidth multipath propagation environment to increase
