Abstract

In this letter, a diversity-achieving quadrature spatial modulation (DAQSM) aided multiple-input multiple-output orthogonal time frequency space (MIMO-OTFS) scheme is proposed, which can provide both transmit diversity and higher spectral efficiency (SE). Through the design of expansion matrices (EMs), the proposed scheme can be conveniently extended to scenarios with more than two transmit antennas. Furthermore, we present the analytical expression of bit error rate (BER) and diversity analysis. Simulation results demonstrate the superior performance of the proposed scheme compared to related schemes in high-mobility scenarios.

分集实现正交空间调制辅助MIMO-OTFS传输

本文提出了一种实现分集的正交空间调制（DAQSM）辅助多输入多输出正交时频空间（MIMO-OTFS）方案，该方案既能提供发射分集，又能提高频谱效率（SE）。通过扩展矩阵的设计，该方案可以方便地扩展到两个以上发射天线的场景。此外，我们给出了误码率（BER）的解析表达式和分集分析。仿真结果表明，在高迁移率场景下，与相关方案相比，该方案具有优越的性能。
