物联网(IoT)和机器对机器(M2M)通信将在未来的通信中发挥重要作用，但目前还没有超可靠的低延迟无线通信理论来指导其设计。对于高度移动的车辆到车辆(V2V)无线通信场景，也应接受异步传输。因此，研究满足异步传输要求的超可靠低延迟无线传输技术显得尤为迫切。通用滤波多载波(UFMC)就是适应这一特点的一种新型的滤波无线传输机制。虽然近年来人们对它的一些性质进行了探索，但很少有文章系统地评价它的性能。本文首先从频谱效率(SE)、误码率(BER)、峰均功率比(PAPR)、载波频偏(CFO)以及各种多径衰落信道、时延(TD)等方面对UFMC系统的性能进行了全面的评估，同时建立了UFMC系统误码率的数学分析模型，推导出了UFMC误码率的精确闭环表达式。此外，还推导了发射机在频域中的等效形式。最后，给出了与UFMC相关的蒙特卡罗仿真结果。结果表明，UFMC存在与其他多载波系统相同的问题，包括较高的PAPR，受CFO的影响，但它有其固有的对时延不敏感或能量有效的优点，并且UFMC的主要负面因素是载波间干扰(ICI)而不是符号间干扰(ISI)，这可能在未来的M2M和V2V通信中发挥重要作用。
The Internet of Things (IoT) and machine-to-machine (M2M) communication will play an important role in future communications, but there is currently no ultra-reliable low-latency wireless communication theory that guides its design. For highly mobile vehicle-to-vehicle (V2V) wireless communication scenarios, asynchronous transmission should also be accepted. Therefore, it is particularly urgent to study ultra-reliable low-latency wireless transmission technology that satisfies asynchronous transmission. Universal Filter Multi-Carrier (UFMC) is a new type of filtering wireless transmission mechanism that meets this character. Although some of its properties have been explored in recent years, there are few articles that systematically evaluate its performance. In this paper, firstly, the performance of the UFMC system is fully evaluated in terms of spectral efficiency (SE), bit error rate (BER), peak-to-average power ratio (PAPR), carrier frequency offset (CFO), as well as various multipath fading channels, effects of time delay (TD), etc. Meanwhile, a mathematical analysis model is established for the BER of UFMC system, and some exact closed-loop expressions of bit error probabilities for UFMC are derived. Moreover, the equivalent form of the transmitter in the frequency domain is derived. Finally, the Monte Carlo simulation results related to UFMC are presented. The results reveal that UFMC suffers from the same problems as other multi-carrier system, including higher PAPR, affected by CFO, but it has its own inherent advantages such as insensitivity to time delay or energy-efficient, and the main negative factor of UFMC is inter-carrier interference (ICI) not inter-symbol interference (ISI), which may play an important role in future M2M and V2V communication.
