| Abstract(in English) | This paper proposes a turbo equalization system applied a dynamic spectrum control technique, which aims at an improvement of link qualities in multi-user environments with the aid of frequency selective MIMO channels correlated among transmit antennas. In general, iterative equalization schemes based on "turbo principle" independently detects user signals even in MIMO channels in the case where EXIT trajectories are perfectly converged. The convergence property is, however, getting worse in higher correlated MIMO channels. This paper clarify the fact that the link qualities are improved by the dynamic spectrum control technique in such scenario. Finally, EXIT and PER analyses are conducted to demonstrate the effectiveness and impact of the proposed approach. |
