Abstract

A novel multiple-input multiple-output (MIMO) space shift keying (SSK) modulation scheme, termed fully signed quadrature space shift keying (FSQ-SSK), is proposed in this paper. Unlike conventional MIMO space modulation techniques (SMTs), the proposed FSQ-SSK utilized the four independent spatial domains provided by the ± in-phase and ± quadrature-phase with the overall potential transmitter (TX) antenna combinations (including the inactive TX antenna case) to increase its spectral efficiency (SE). Hence, the attainable data rate of the proposed FSQ-SSK is directly linearly increased with the number of TX antennas. Moreover, the proposed FSQ-SSK can operate with any number of TX antennas ≥2. As a result, the number of TX antenna is not restricted to being equal to

any longer (i.e., it is adaptable), where ı is any positive integer number >0. Numerical computer simulation results illustrate the superiority of the proposed FSQ-SSK as at 10 dB signal-to-noise ratio (SNR), it achieves an average ∼5.8 dB saving compared to the up-to-date SMTs with satisfactory computational complexity.

全签名正交空间移位键控MIMO调制

提出了一种新的多输入多输出（MIMO）空间移位键控（SSK）调制方案，称为全签名正交空间移位键控（FSQ-SSK）。与传统的MIMO空间调制技术（smt）不同，所提出的FSQ-SSK利用±同相和±正交相提供的四个独立空间域，与整体潜在发射机（TX）天线组合（包括非活动TX天线情况）来提高其频谱效率（SE）。因此，所提出的FSQ-SSK的可达到的数据速率与TX天线的数量直接线性增加。此外，所提出的FSQ-SSK可以在任意数量的TX天线（≥2）下工作。因此，TX天线的数量不再局限于等于2个（即，它是可适应的），其中，2个是任意正整数>；0。数值计算机仿真结果表明了所提出的FSQ-SSK的优越性，在10 dB信噪比（SNR）下，与最新的smt相比，它实现了平均~ 5.8 dB的节省，并且具有令人满意的计算复杂度。
