Abstract
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.
Highlights
Over the last few years, the continuous application of various new wireless technologies such as multiple antennas, multi-carrier transmission, etc., basically meets the people’s requirements for high bandwidth and reliability
The difference between inter-symbol interference (ISI) and inter-carrier interference (ICI) is that the ISI is caused by trailing of symbols which can be eliminated by accurate channel estimation, and ICI is caused by carrier frequency offset which causes interference between adjacent carriers
We firstly evaluate the spectral efficiency of three waveforms, and the peak-to-average power ratio (PAPR) of Orthogonal frequency division multiplexing (OFDM), Universal Filter Multi-Carrier (UFMC), SCFDE [30], filter bank based multi-carrier (FBMC), and LFBMC [31] is simulated
Summary
Over the last few years, the continuous application of various new wireless technologies such as multiple antennas, multi-carrier transmission, etc., basically meets the people’s requirements for high bandwidth and reliability. Effectively supporting multiple types of services, provided with high data rate, large bandwidth, multiple access, low BER and large throughput need to consider Under these conditions, the traditional wireless air interface technology can not meet a diverse set of services in different scenarios. It is urgent to propel the small packet and low-latency wireless transmission technology that mainly provides services for IoT or M2M For this purpose, UFMC [10], [11] is proposed as a new filtering transmission mechanism to meet this demand.
