Design Of Spatial Channel Modeling And Analyzing Software

Because multiple input multiple output (MIMO) technology can improve the spectrum efficiency, it attract more and more attention in the wireless communication field. For the application of MIMO, the different propagation at different spatial direction is the main focus of many research institutes. Therefore, different from single antenna technology, in the research of MIMO, especially in the research of beam-forming, which is related to the spatial angle, besides fading and delay, the statistical performance of angle should be considered.This paper is to design and develop a spatial channel modeling and analyzing software, which has friendly user interface and is easy to use. The software can describe the urban macro cell, urban micro cell as well as the suburban macro cell. And the parameter of channel model can be configured by user. It also analyze the delay spread, the joint distribution of power, delay and degree of arrival, the joint distribution of power and delay, the joint distribution of power and degree of arrival, the variation of Doppler frequency with time, the time domain channel impulse response, the calculation of multiple path. It's also able to generate whole report automatically. At first, this paper introduced the MIMO in detail. The second chapter explained the spatial channel model in the software. The third chapter introduced the design of the software. The fourth chapter depicted the all function of the software. The last chapter is conclusion of the paper.
