Abstract

This paper introduces a realistic MIMO platform which was created according to the IEEE 802.16e-2005 standard (WiMAX). The MIMO-WiMAX platform is computationally efficient and capable of simulating space-selective, time-selective and frequency selective fading conditions. The simulator can simulate any arbitrary power-delay profile without increasing the receivers sampling frequency. The simulator has the capability of simulating quasi-static fading conditions as well as block-fading conditions. The platform was used to simulate recent coding technologies which consists of space-time codes, space-frequency codes and space-time-frequency codes. The results obtained illustrates the effects of simulating these modern coding techniques on a MIMO-WiMAX platform in realistic mobile environments which consists of a large number of multipath delays and correlation between antennas at the transmitter and receiver. The codes simulated form a set of newly defined codes which could be incorporated into the standard complementing the current single-symbol maximum likelihood codes to be used as a guideline in designing real world MIMO-WiMAX systems.
