摘要:

随着智慧城市、人工智能、边缘计算等技术的快速发展,未来物联网将面临海量终端接入和频谱资源紧张等问题,基于高频谱效率的非正交安全接入(HSESA)提出一种双重非正交多址接入(D-NOMA)技术,结合了码域的非正交接入和频域的非正交复用,具有很好的频谱效率性能。发送端和接收端被优化,多用户通过稀疏码本直接映射到重叠的子载波上。通过在莱斯信道下的性能分析表明,D-NOMA比HSESA具有更好的误码率性能。

Abstract:

With the rapid development of many technologies such as smart city,artificial intelligence and edge computing,the future Internet of things will face the problems of massive terminal access and spectrum resource constraints.A dual non-orthogonal multiple access (D-NOMA) technology based on high spectral efficiency secure access (HSESA) was proposed,which combined non-orthogonal access in the code domain and non-orthogonal multiplexing in the frequency domain,and had good spectral efficiency performance.The sender and receiver were optimized,and multiple users were mapped directly to the overlapping subcarriers through the sparse codebook.The performance analysis under the Rician channel shows that D-NOMA has better bit error rate performance than HSESA.

Key words: Internet of things, dual non-orthogonal multiple access (D-NOMA), high spectral efficiency secure access (HSESA), spectral efficiency, bit error rate
