Exhaustive research is being done to establish the technologies and standards of the fifth generation (5G) of wireless communication systems. Some of the most challenging requirements of 5G systems are to increase the spectral efficiency and the capacity by a factor of 10 and 1,000, respectively. New technologies must offer an adequate framework for the 5G uses cases, which will enable higher capacities and the flexibility to adapt to dynamic scenarios. To cope with these challenging demands, a compelling approach is to exploit the current radio service bands by means of spectrum sharing and cooperation techniques, which alleviate the bandwidth requirements. In addition, advanced modulation schemes have a fundamental role in ensuring the best usage of the spectrum available in band‐limited systems. In this manuscript, we present the ultra‐wideband (UWB) technology as a prospective solution for 5G picocells and femtocells. Its main feature is its capability to operate simultaneously, without introducing interference, with current radio services on an unlicensed basis. We report experimental results reaching data rates up to 35 Gbit/s using the multiband approach of carrierless amplitude phase (MB‐CAP) modulation. To validate the versatility of the proposed system, our experimental tests were performed under the UWB regulations defined by the United States' Federal Communications Commission (FCC), the European Electronic Communications Committee (ECC), and the Russian State Committee for Radio Frequencies (SCRF). The regulations chosen provide diversity enough to demonstrate the capacity of MB‐CAP modulation to comply with worldwide regulations.

超宽带技术:5G超小型蜂窝网络的预期解决方案

正在进行详尽的研究以建立第五代(5G)无线通信系统的技术和标准。5G系统最具挑战性的要求是将频谱效率和容量分别提高10倍和1000倍。新技术必须为5G用例提供适当的框架,这将使更高的容量和灵活性能够适应动态场景。为了应对这些挑战性需求,一种令人信服的方法是通过频谱共享和协作技术来利用当前的无线电服务频段,从而减轻带宽需求。此外,高级调制方案在确保频带受限系统中可用频谱的最佳利用方面起着基本作用。在这份手稿中 我们将超宽带(UWB)技术作为5G微微小区和毫微微小区的前瞻性解决方案。它的主要特点是可以在无许可的情况下与当前的无线电服务同时运行而不会造成干扰。我们报告了使用无载波幅度相位(MB-CAP)调制的多频带方法达到高达35 Gbit / s的数据速率的实验结果。为了验证所提议系统的多功能性,我们的实验测试是根据美国联邦通信委员会(FCC),欧洲电子通信委员会(ECC)和俄罗斯国家无线电频率委员会(SCRF)定义的UWB规定进行的)。所选法规提供的多样性足以证明MB-CAP调制的能力,以符合全球法规。
