Abstract

In this research, an experimental study has been carried out to measure the MIMO performance in LOS and NLOS indoor environment by using a 2 times 2 MIMO system where the MSAA is used as the receiving antenna with different array spacing. The EVM was measured to demonstrate the performance of the MSAA in the MIMO communication systems. It is found that larger array spacing can improve the EVM, and the array spacing has more influence on the EVM of the first stream than the second stream.
