Modelling, Simulation and Capacity Analysis of Spatial Channel Models in MIMO System
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 5
Abstract
Future wireless communication systems will utilize the spatial properties of the wireless channel to improve the spectral efficiency and thus increase capacity. This is realized by deploying multiple antennas at both the transmitter and receiver. Due to the unpredictable nature of the wireless channel, a common approach is to model its effects statistically. A few large world-wide co operations, like the third generation partnership project (3GPP) have developed channel models intended for reference and standardization use. These models are partly based on some bulk parameters that describe the characteristics of the channel over larger areas of several wavelengths. Such parameters include shadow fading, angle spread, and delay spread, etc. In the spatial channel model (SCM) these large-scale parameters are assumed independently between separate links, i.e., channel modelling, propagation between different mobile and base stations. This paper focuses on investigation of MIMO system capacity using the Spatial Channel Model (SCM) and Channel Capacity, Spatial Autocorrelation for different channel environments, proposed by standardization bodies (3GPP-3GPP2) for third generation systems. This SCM offers three environments such as suburban macro-cell, urban macro-cell and urban micro-cell parameters are obtained by using MATLAB 7.12.0.
