Abstract

As an attractive option for multiple-input multiple-output (MIMO) systems, generalized space shift keying (GSSK) is greatly affected by the Hamming distance of spatial vectors. In this letter, a new scheme called hash function-assisted GSSK (H-GSSK) is proposed. More concretely, the proposed scheme uses a hash function to generate spatial vectors with enlarged Hamming distance. In addition, the analyses of the average Hamming distance, detection complexity, and design complexity are conducted to evaluate the overall system performance. Besides, obtained Monte Carlo simulation results demonstrate the proposed H-GSSK scheme enables a low bit error rate (BER) and comparable complexity as that of existing schemes.

哈希函数辅助广义空间移位键控调制

广义空间移位键控（GSSK）是多输入多输出（MIMO）系统的一种有吸引力的选择，它受空间矢量汉明距离的影响很大。本文提出了一种新的哈希函数辅助GSSK （H-GSSK）方案。更具体地说，该方案使用哈希函数生成具有放大汉明距离的空间向量。此外，对平均汉明距离、检测复杂度和设计复杂度进行了分析，以评估系统的整体性能。此外，Monte Carlo仿真结果表明，所提出的H-GSSK方案具有较低的误码率和与现有方案相当的复杂度。
