Physical statistical modelling of MIMO channel based on Rician distribution

摘要

Due to spectral efficiency enhancements, Multiple Input Multiple Output (MIMO) technology will be applied for next generation communications systems in the near future. Accurate MIMO model is very important to analyse statistical properties of the channel and predict performance of the transmission system. The paper proposes a physical-statistical model for MIMO system combining ray-tracing and Rician model. By simulating in a block of city, the work gives the statistical properties and capacity of the MIMO system. The results show that the model can be applied to the MIMO system and have the advantage of a precise description about propagation and a low computational cost.
