Exploring the performance of turbo MIMO equalization in real field scenarios

Abstract

This paper describes the methodology and the results of performance investigations of the turbo MIMO equalizer concept for broadband MIMO systems. Different application setups are introduced and realistic simulations based on measured propagation data are described. Relationships between the propagation characteristics, the antenna configurations, and the achievable bit error rates are shown. Although in many of the considered constellations turbo MIMO detection appears feasible in real field scenarios, there exist cases with poor performance as well, indicating that for practical applications a technique for link adaptation of the transmitter and receiver processing to the environment is necessary.
