Performance of MIMO over SUI Channels for IEEE 802.16 Networks
Abstract
Stanford University Interim (SUI) channel model has been proposed for simulations, design, development and testing of technologies suitable for IEEE 802.16 networks. SUI channel model proposes a set of six empirical time-dispersive channels for three typical terrain types. Most of the simulation studies for IEEE 802.16 networks involving Multi-Input Multi-Output (MIMO), either use a flat fading channel model or adopt an existing analytical/standard model, such as Kronecker model, 3GPP, IEEE 802.11 Broadband wireless models, and Pedestrian model A-B. Although this reduces the complexity of the channel models, it results in lower accuracy. This paper presents the evaluation of Bit Error Rate (BER) performance of various MIMO techniques for 2×2 and 4×4 antenna configurations, over SUI channel models. The encoding and decoding equations for Space-Time Block Code (STBC) \(\mathcal{G}4\) and Spatial Multiplexing (SM) for frequency selective channels are also presented.
