Directional measurement and analysis of propagation path variations in a street micro-cell scenario

摘要: We present results from field experiments in a street-micro scenario downtown Tokyo, which have been carried out to explore the main mechanisms leading path parameter variations. The measurements using wideband-vector-channel-sounder. transmitter (mobile station) was equipped with an omni-directional antenna whereas at receiver (base uniform linear array has used. parameters of dominant propagation paths estimated high-resolution estimation algorithms (joint unitary ESPRIT and SAGE). From these three variations discovered. observed channel characteristics are useful for development realistic directional urban multi models.
