Pilot-Aided Channel Estimation for Universal Filtered Multi-Carrier

2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015
Universal Filtered Multi-Carrier (UFMC, a.k.a. UF-OFDM) is a novel multi-carrier modulation technique, which aims at replacing OFDM for next generation wireless communication systems (5G). It is a generalization of OFDM and filter bank based multi-carrier (FBMC-FMT), which combines the advantages of OFDM and FBMC while avoiding its main drawbacks. UFMC

DFT-Spread Universal Filtered Multi-Carrier for 5G

2016 2nd IEEE International Conference on Computer and Communications (ICCC), 2016
Internet of things (IoT) and machine-type-communication (MTC) will play an important role in 5G communication systems. Combining the simplicity of Orthogonal Frequency Division Multiplexing (OFDM) with the advantages of Filtered Bank Based Multi-Carrier (FBMC), Universal Filtered Multi-Carrier (UFMC) is robust to frequency offset and timing offset, and

Adaptive Modulation and Filter Configuration in Universal Filtered Multi-Carrier Systems

IEEE Transactions on Wireless Communications, 2018
Universal filtered multi-carrier (UFMC) is a potential waveform technology, which can efficiently combat different carrier frequency offsets (CFOs) of multiple users. First, adaptive modulation and power allocation are applied for each subcarrier to meet a preset bit error rate (BER) requirement by ignoring CFOs. Then, we prove that different CFOs will

Universal filtered multi-carrier transmission with active interference cancellation

2015 International Conference on Wireless Communications & Signal Processing (WCSP), 2015
Orthogonal Frequency Division Multiplexing (OFDM) has high subcarrier side-lobe levels, which makes it vulnerable to time-frequency misalignments and thus may be not suitable for asynchronous transmission in the future 5G systems. Therefore, it is necessary to design new multi-carrier modulation technologies.

Performance evaluation of hybrid transform for universal filtered multi‐carrier system

Transactions on Emerging Telecommunications Technologies, 2022
AbstractHigh peak to average power ratio (PAPR) is viewed as a serious limitation of all multi‐carrier systems. In this article, a companding transform with clipping technique is proposed for universal filtered multi‐carrier (UFMC) system. The proposed companding transform successfully reduces the PAPR by expanding the small amplitude signals and ...

Universal filtered multi-carrier with dynamic sub-band allocation

2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT), 2016
In this paper, we introduce a novel framework to allocate sub-bands dynamically for Universal Filtered Multi-Carrier (UFMC). Compared with the conventional uniform sub-band allocation, the proposed framework adjusts the size of sub-band based on the user demands, which improve the utilization efficiency of the subcarriers.

On the cyclostationarity of Universal Filtered Multi-Carrier UFMC

AEU - International Journal of Electronics and Communications, 2018
Abstract In order to meet the explosion of connected devices with their heterogeneous applications, the upcoming 5G systems focus on the design of spectrally efficient waveforms. Universal Filtered Multicarrier (UFMC) is one of the major waveforms contenders that offers low out of band emissions, compatibility with the existing Multiple Input ...

Improved Performance of 64/128-QAM Universal Filtered Multi-carrier PON

26th Optoelectronics and Communications Conference, 2021
We experimentally demonstrated an intensity-modulation direct-detection UFMC transmission system over 30-km standard single mode fiber. The BER performance of 64-QAM and 128-QAM UFMC signals are measured and compared with that of the OFDM signals.
