摘要

本文提出了一种由自适应调制、正交频分复用(OFDM)、高阶空频分组编码(SFBC)和天线选择相结合的新方案。该方案利用空频分组码、OFDM和自适应调制的优点，在频率选择性衰落信道上为无线通信提供高质量的传输。研究了该系统的频谱效率和编码增益优势。研究表明，采用自适应调制的天线选择可以大大提高传统的SFBC-OFDM系统的性能。

Variable-rate OFDM systems with selective antenna diversity and adaptive modulation

In this article, a new scheme consisting of a combination of adaptive modulation, orthogonal frequency division multiplexing (OFDM), high order space-frequency block coding (SFBC), and antenna selection is presented. The proposed scheme, exploits the benefits of space-frequency block codes, OFDM and adaptive modulation to provide high quality of transmission for wireless communications over frequency selective fading channels. We examine the spectral efficiency and coding gain advantages of the proposed system. It is shown that antenna selection with adaptive modulation can greatly improve the performance of the conventional SFBC-OFDM systems.
