Abstract

This paper proposes a new adaptive modulation (AM) scheme for closed-loop MIMO transmission over wireless correlated channels. Two correlation-based channel models are considered to illustrate the interest of the proposed solution in realistic environments representative of transportation systems. Several simulation results for different transmission scenarios are presented and discussed. It is shown that the proposed AM approach outperforms several precoding schemes and provides full diversity order.
