Semi-deterministic channel model for MIMO systems Part-II: results

This article presents the results of applying `single interaction scattering reflecting' (SISTER) model to different multiple-input multiple-output (MIMO) channels. The SISTER model is a semi-deterministic channel model which is described in details in Part-I of this article. MIMO performance is investigated for outdoor and indoor environments considering both line of sight (LOS) and non-line of sight (NLOS) cases. Different results are obtained by changing antenna array parameters such as spacing and number of elements and antenna half power beam width (HPBW), as well as environment parameters such as ground`s and walls` conductivity, and number and distribution of scatterers. In addition, space and angle diversity methods are compared for most of the studied cases. As the results show for most scenarios, the MIMO performance may be further improved by using multi-beams (angle diversity) rather than multi-antenna elements (space diversity).
