Embodiment Construction

[0061] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0062] 1) Establish the non-physical model correlation matrix of the multiple-input multiple-output (MIMO) communication system channel:

[0063] R H = R H Tx ⊗ R H Rx - - - ( 3 )

[0064] That is, the correlation matrix of the channel is the transmitter antenna correlation matrix R H Tx and receiver antenna correlation matrix R H Rx The Kronecker product, where the transmitter antenna correlation matrix R H Tx and receiver antenna correlation matrix R H Rx is calculated by the spatial correlation function. After the channel correlation matrix is ​​known, the channel fading coefficient of each resolvable path...

Abstract

This invention relates to multiple input and output communication system signal one non-physical module establishing and artificial method, which comprises the following steps: Firstly establishing multiple input and output communication system non-physical relative matrix; then generating independent multiple path declining channel; then valuating the generated independent declining parameters; finally computing space relative matrix and using third partner plan to give angle power spectrum intensity form to get space relative parameters and to use MIMO system channel non-physical module formula to get the channel space relative matrix.

Description

technical field [0001] The invention relates to an optimal design method of a wireless communication system, in particular to a modeling and simulation method of a channel of a multi-input multi-output communication system. Background technique [0002] With the development of wireless communication technology, people's demand for wireless communication capacity is increasing rapidly. On the other hand, the available wireless spectrum is limited, and it is impossible to meet the requirement of communication capacity expansion if the utilization rate of the communication spectrum is not significantly improved. Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) wireless communication systems have good anti-fading and anti-noise capabilities, so that huge capacity can be obtained. Therefore, in a wireless channel with limited power bandwidth, MIMO technology is a space diversity technology to achieve high data rate, improve system capacity and transmission q...
