MIMO Channel Optimization In Indoor Line-Of-Sight (LOS) Environment
This paper optimizes the narrowband MIMO channel gain by considering the channel parameters of the Line-of-Sight (LOS) rays arriving at the receiving point. LOS MIMO is one possible technology for increasing the channel capacity of wireless communication. The performance of this channel gain is evaluated by calculating the channel capacity and compared with other channel capacity values. The theoretically achievable Shannon capacity is a function of the channel between transmitters and receivers. One of the mathematical methods from linear algebra, namely Singular Value Decomposition (SVD) is used for diagonalizing the channel matrix and finding the eigenvalues. All the experiments are conducted at the main building portico of Mandalay Technological University, the Republic of the Union of Myanmar in LOS environment at a carrier frequency of 2.4 GHz. The performance comparison of channel capacity with respect to the experimental data is implemented with the help of MATLAB programming language.
