Wireless communication technology is the main reason for the advancement to mobile users. So each user demands for a separate frequency spectrum. But there is a limited frequency spectrum band. Hence there is need of an efficient communication system which first evaluates the need of frequency and then provides the frequency band to that user smartly. Cognitive Radio (CR) Technology is based on software defined radios (Mitola in Cognitive radio—an integrated agent architecture for software defined radio (Ph.D. Dissertation). KTH Royal Institute of Technology, Kista, 2000). When the frequency spectrum is used by the authorized primary user (PU), then cognitive radio provide the remaining available bandwidth to the secondary user (SU) which has very less interference with primary user. The main work of cognitive radio is to check the spectrum and find the available free channels for secondary users without affecting the primary user’s work. Universal Filtered Multicarrier (UFMC) technique gives better performance over other multicarrier techniques in term of PAPR. The work presented here is unique and novel in the sense that we have tried to incorporate the UFMC technique simultaneously in comparison with applied GFDM multicarrier modulation technique in the same wireless scenario for highlighting the contrast in the study presented here. The probable limitations of the proposed solutions after carrying out rigorous simulation testing on Matlab version 2018a have also been discussed.

GFDM和UFMC在不同窗口约束下的下一代认知无线电通信的比较性能分析

无线通信技术是向移动用户发展的主要原因。因此,每个用户都需要一个单独的频谱。但是频谱范围有限。因此,需要一种有效的通信系统,该系统首先评估频率的需求,然后将频带智能地提供给该用户。认知无线电(CR)技术基于软件定义的无线电(认知无线电中的Mitola –一种软件定义无线电的集成代理体系结构(博士学位论文),KTH皇家理工学院,基斯塔,2000年)。当频谱被授权的主要用户(PU)使用时,认知无线电将剩余的可用带宽提供给次要用户(SU),而对次要用户的干扰非常小。认知无线电的主要工作是检查频谱并找到次要用户可用的免费频道,而不会影响主要用户的工作。就PAPR而言,通用滤波多载波(UFMC)技术提供了优于其他多载波技术的性能。在相同的无线场景中,我们试图将UFMC技术与应用的GFDM多载波调制技术同时纳入,以突出此处研究的对比,因此,本文提出的工作是独特而新颖的。还讨论了在Matlab 2018a版上进行严格的仿真测试后,所提出解决方案的可能局限性。就PAPR而言,通用滤波多载波(UFMC)技术提供了优于其他多载波技术的性能。在相同的无线场景中,我们试图将UFMC技术与应用的GFDM多载波调制技术同时纳入,以突出此处研究的对比,因此,本文提出的工作是独特而新颖的。还讨论了在Matlab 2018a版上进行严格的模拟测试后,所提出解决方案的可能局限性。就PAPR而言,通用滤波多载波(UFMC)技术提供了优于其他多载波技术的性能。在相同的无线场景中,我们试图将UFMC技术与应用的GFDM多载波调制技术同时纳入,以突出此处研究的对比,因此,本文提出的工作是独特而新颖的。还讨论了在Matlab 2018a版上进行严格的仿真测试后,所提出解决方案的可能局限性。在相同的无线场景中,我们试图将UFMC技术与应用的GFDM多载波调制技术同时纳入,以突出此处研究的对比,因此,本文提出的工作是独特而新颖的。还讨论了在Matlab 2018a版上进行严格的仿真测试后,所提出解决方案的可能局限性。在相同的无线场景中,我们试图将UFMC技术与应用的GFDM多载波调制技术同时纳入,以突出此处研究的对比,因此,本文提出的工作是独特而新颖的。还讨论了在Matlab 2018a版上进行严格的仿真测试后,所提出解决方案的可能局限性。
