摘要

研究发现，70%的频谱没有被使用。能量、特征检测和匹配滤波器只是过去提出的一些技术。在本研究中使用匹配滤波器来确定频谱是否空闲或已被主用户使用。在这种情况下，如果主用户不需要license频谱，则可能会导致从用户访问该频谱。利用MATLAB仿真软件以OFDM模型(建议模型)和NOMA模型的输出信号作为输入进行仿真。在本研究的后期，我们将对一些指标进行检查，并与当前技术进行对比，包括检测概率(PD)和误报概率(PFA)。

A mathematical investigation of multi-carrier waveform with AI based matched filter detection

Research found that 70% of the spectrum is not being used. Energy, feature detection, and matched filters are just a few of the techniques that have been suggested in the past. A matching filter is used in this study to determine whether a spectrum is free or already in use by the primary user. In this case, if the licensed spectrum for a primary user is not needed, a secondary user may access it. The simulation is carried out by the MATLAB simulation software using the output signals from the OFDM model (proposed model) and NOMA model as inputs. Later in this study, a number of metrics are examined and contrasted with current technology, including probability of detection (PD) and probability of false alarm (PFA).

期刊介绍： The Journal of Interdisciplinary Mathematics (JIM) is a world leading journal publishing high quality, rigorously peer-reviewed original research in mathematical applications to different disciplines, and to the methodological and theoretical role of mathematics in underpinning all scientific disciplines. The scope is intentionally broad, but papers must make a novel contribution to the fields covered in order to be considered for publication. Topics include, but are not limited, to the following: • Interface of Mathematics with other Disciplines • Theoretical Role of Mathematics • Methodological Role of Mathematics • Interface of Statistics with other Disciplines • Cognitive Sciences • Applications of Mathematics • Industrial Mathematics • Dynamical Systems • Mathematical Biology • Fuzzy Mathematics The journal considers original research articles, survey articles, and book reviews for publication. Responses to articles and correspondence will also be considered at the Editor-in-Chief’s discretion. Special issue proposals in cutting-edge and timely areas of research in interdisciplinary mathematical research are encouraged – please contact the Editor-in-Chief in the first instance.
