MIMO/SA Multi-antenna Space-time Channel Modeling
摘要
Abstract
Based on correlation matrix method. Multiple-input and Multiple-output(MIMO) channel coefficient matrix can be obtained by calculating the correlation coefficient between two antennas and MIMO correlation matrix. The steering vector and beam-forming vector of Smart Antenna(SA) are added to the MIMO channel coefficient matrix to form MIMO/SA channel matrix, so that MIMO/SA multi-antenna space-time channel is modeled. A channel simulation platform is established to simulate and analyze MIMO/SA channel in time domain, frequency domain and space domain. Simulation results show that the model has a good channel directivity gain and the channel properties in space, time and frequency meet the demands of 3GPP TR 25.996, and it is useful for designing and optimizing MIMO/SA multi-antenna system and the analysis of channel capacity.关键词
