چکیده
The modulated scattering array antenna (MSAA) is composed of one normal antenna element and several modulated scattering elements (MSE). In this report, a 2-element MSAA is used as the receiving antenna in a 2 by 2 multiple input multiple output (MIMO) system. The MIMO performance of the MSAA with various array spacing is measured to investigate experimentally the relation between the array spacing and the MIMO performance of the MSAA in the Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) indoor environment. It is found that the Error Vector Magnitude (EVM) and the Channel Capacity which reflect the MIMO performance can be affected by the array spacing. Furthermore, the EVM is complementary with the channel capacity.

متن کاملGeometric Modelling of a Spatially Correlated Mimo Fading Channel
For a single antenna channel, Shannon’s classical capacity formula predicts a capacity increase of approximately 1 bit/cycle for every 3 dB increase in signal to noise ratio (SNR). Consequently in multiple antenna arrays, with n antenna elements, the increase in capacity can be in the order of the number of antenna elements, n more bits/cycle for each 3dB increase in SNR. This tremendous gain i...
متن کاملSource Location Estimation Using Phaseless Measurements with the Modulated Scatter- Ing Technique for Indoor Wireless Environ- Ments
This paper proposes the source location estimation technique with the modulated scattering technique (MST) for indoor wireless environments. The uniform circular scatterer array (UCSA) that consist of five optically modulated scatterers as array elements and a dipole antenna at the center of the UCSA is employed for estimating a source location from the impinging signal. In contrast with a conv...
