我们提出了一种用于使用具有可重构辐射方向图的天线的多输入多输出（MIMO）正交频分复用（OFDM）系统的空频（SF）块编码方案。在该系统中，假设发射机侧天线阵列的每个元件都是可重新配置的，以便它可以独立地改变其辐射方向图的物理特性。所提出的块码是全速率的，并且受益于频率选择性衰落信道上的空间、频率和可重构辐射方向图状态多样性。我们提供仿真结果来证明所提出的块编码技术的性能，并与 MIMO-OFDM 系统中先前的 SF 编码方案进行比较。结果表明，与其他可用的 SF 代码相比，所提出的代码实现了更高的分集和编码增益。
We propose a space-frequency (SF) block coding scheme for a multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) system using antennas with reconfigurable radiation patterns. In this system, each element of the antenna array at the transmitter side is assumed to be reconfigurable so that it can independently change the physical characteristics of its radiation pattern. The proposed block code is full rate and benefits from spatial, frequency, and reconfigurable radiation pattern state diversity over frequency-selective fading channels. We provide simulation results to demonstrate the performance of the proposed block coding technique and make comparisons with that of the previous SF coding schemes in MIMO-OFDM systems. The results indicate that the proposed code achieves higher diversity and coding gain compared to other available SF codes.
