| 摘 要： | INTRODUCTION Many adaptive modulation (AM) schemes have been proposed for multi-input and multi-output (MIMO) and its derivations to increase the data throughput (June and Rao, 2002; Zhou and Vucetic, 2004a; 2004b; Chen et al., 2004; Zhou and Giannakis, 2004b). By using some kinds of greedy algorithms, all of these AM schemes try to maximize the trans-mission rate for a given transmission power. Their performances under different conditions have been studied deeply. The AM-MIMO w…

| Abstract: | Adaptive modulation (AM) is an effective technique to approach the theoretical bound of multi-input and multi-output (MIMO)
channel. In most previous studies, the AM parameters were obtained by maximizing the transmission rate for a given total transmit
power. In this paper, a novel AM-MIMO algorithm is presented, which is based on minimizing total transmit power when the link’s
QoS requirements are given. By taking the QoS requirements into account directly, the proposed algorithm not only makes the
system more flexible, but also makes the cross layer design of wireless network easier. At last, the numerical results of
the proposed scheme are presented.
