摘要

循环平稳频谱(CS)方法是最好的方法之一，因为它可以有效地检测低信噪比(SNR)的空闲频谱。为了在噪声环境中区分信号，收集更多有助于更好地分析信号的数据，并使用频谱相关性进行可靠的框架建模，CS实现了最佳性能特性。高度复杂性被视为CS的缺点之一。在本文中，我们提出了一种新的5G波形的CS算法。通过限制循环平稳特性和信号自相关的计算，降低了CS的复杂度。为了评估5G波形的性能，提出了基于认知无线电(CR)的能量检测(ED)和CS频谱感知算法。研究结果表明，所提出的CS算法具有较好的检测效果，比常规标准提高了2 dB。

Cyclostationary and energy detection spectrum sensing beyond 5G waveforms

The cyclostationary spectrum (CS) method is one of the best at what it does because it effectively detects idle spectrum with low signal-to-noise ratios (SNR). In order to distinguish the signal in a noisy environment, gather more data that aids in a better analysis of signals, and use spectral correlation for dependable framework modelling, CS achieves optimal performance characteristics. High intricacy is seen as one of the CS's shortcomings. In this article, we suggest a novel CS algorithm for 5G waveforms. By restricting the computation of cyclostationary characteristics and the signal autocorrelation, the complexity of CS is reduced. To evaluate the performance of 5G waveforms, the Energy Detection (ED) and CS spectrum sensing algorithms based on cognitive radio (CR) are presented. The results of the study show that the suggested CS algorithm did a good job of detection and gained 2 dB compared to the conventional standards.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
