Simulation of Multiple Input Multiple Output based 802.16 WiMAX Technology using Matlab
This Paper shows how to simulate multiple-input multiple-output (MIMO) multipath fading channels based on the IEEE 802.16 channel models for fixed wireless applications. This paper uses a multiple-input multiple-output (MIMO) multipath fading channel System object with two transmit antennas, one receive antenna, and a rounded Doppler spectrum object. The WiMAX IEEE 802.16 channel models for fixed wireless applications are proposed for scenarios where the cell radius is less than 12 km, the directional antennas at the receiver are installed under-the-eaves/windows or on the rooftop, and the base station (BS) antennas are 10 to 35 m in height. The 802.16 channel models contains a set of path loss models including shadowing i.e. suburban, urban and a multipath fading model, which describes the multipath delay profile, the K-factor distribution, and the Doppler spectrum. The antenna gain reduction factor, due to the use of directional antennas, is also characterized. In modern world wireless communication systems are involved in every part of life. WiMAX is the upgraded and current version of wireless system with IEEE standard 802.16. WiMAX technology can be used to reduce the drawbacks of the available wireless communication such as low data rate, small coverage area, security lack. In this paper, initially we analyzed the basic concept of WiMAX, and then we tested transmission and reception of WIMAX technology by using MATLAB simulation.
