本文提出了一种新的自适应正交频分复用传输方案，其中自适应编码和调制(ACM)和所需的信令开销被联合优化以最大化有效数据速率。在所考虑的时分双工(TDD)系统中，发射机只向接收机发送最重要的ACM参数，接收机基于一种新的最大后验概率(MAP)算法对调制方案进行分类。室内传播场景的仿真结果表明，新技术具有较高的有效带宽效率，可以看作是自动调制分类(MC)和纯基于信令的传输概念的结合。
This paper proposes a novel adaptive Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme in which adaptive coding and modulation (ACM) and the required signaling overhead is jointly optimized to maximize the effective data rate. In the considered time-division duplex (TDD) system, the transmitter signals only the most important ACM parameters to the receiver which classifies the modulation schemes based upon a novel maximum-a-posteriori (MAP) algorithm. Simulations results for indoor propagation scenarios show a superior effective bandwidth efficiency of the new technique which can be regarded as a combination of automatic modulation classification (MC) and a pure-signaling-based transmission concept.
