摘要

摘要认知无线电（Cr）是最有前途的发展之一，它结合了光学非正交多址（O-NOMA）方法来提高第五代（5G）频谱的使用效率。在这项工作中，我们提供了一种基于循环平稳特征检测（CFD）和能量检测（ED）的混合方法。它所基于的虚警概率（PFA）用于选择使用哪种频谱感知（SS）方法。当PFA小于0.5时，选择ED；否则，MF是。使用Matlab-2016仿真，参考误码率（BER）、信噪比（SNR）、检测概率（PD）和PFA等几个指标，研究了O-NOMA中建议的检测方法。

Improving and analysing the spectral access performance of QAM-64 optical NOMA using a hybrid ED-CSD algorithm

Abstract Cognitive radio (Cr) is one of among the most promising developments, which combines optical non-orthogonal multiple access (O-NOMA) methods to increase the fifth generation (5G) spectrum’s usage efficiency. In this work, we provide a hybrid approach based on cyclic stationary feature detection (CFD) and energy detection (ED). The probability of false alarm (PFA), on which it is based, is used to choose which spectrum sensing (SS) approach to use. When PFA is less than 0.5, the ED is chosen; otherwise, the MF is. The suggested detection method in O-NOMA is investigated using Matlab-2016 simulation with reference to several metrics, such as bit error rate (BER), signal-to-noise ratio (SNR), probability of detection (PD), and PFA.
