The paper firstly analyzes the channel characteristic of the smart antennas systems based on spatial channel model(SCM), which includes the time-correlated feature, frequency-correlated feature, spatial-correlated feature and its corresponding spectral features for Suburban Macro, Urban Macro and Urban Micro. Furthermore we study the fading depth of it. At last, considerable simulations are utilized...
Applying smart antennas to the communication system with FDD mode is still a difficulty which remains to be answered, due to the existing frequency difference between uplink and downlink. In this paper, downlink beam forming was implemented in terms of transmission-receiving reciprocity theorem of antennas and receiver feedback of fade parameters. According to simulation analysis, the results reveal...
