A Novel Pilot Superimposition Method for UFMC Systems
Proceedings of the 2nd International Conference on Telecommunications and Communication Engineering, 2018In this letter, a novel pilot superimposition method is proposed for universal filtered multi-carrier (UFMC) systems to sounding channel. The pilot signals are superimposed onto some special positions in the filter ramps to make sure that the interferences between data and pilot signals are kept relatively low. Simulation results show that the proposed

A Review of PAPR Reduction Techniques for UFMC Waveform
2020 4th International Symposium on Multidisciplinary Studies and Innovative Technologies (ISMSIT), 2020This paper addresses the usage of the Universal Filtered Multi Carrier (UFMC) band. UFMC is a multicomponent network modulation technique (5G). In this paper we discuss the different modulation technologies for 5 G technology and support the need for UFMC technology in wireless 5 G communication.

The effect of carrier frequency offsets on an IDMA-UFMC system
2017 Eighth International Workshop on Signal Design and Its Applications in Communications (IWSDA), 2017We consider a structure which integrates the idea of interleave-division multiple access (IDMA) into a universal-filtered multicarrier (UFMC) system. The constructed IDMA-UFMC system is compared to the IDMA-OFDM system. In either system, several adjacent subcarriers are grouped as a subband which is shared by two users using different interleavers. The

Low-complexity PTS PAPR reduction scheme for UFMC systems
Cluster Computing, 2017In this study, a low-computational-complexity partial transmit sequence (PTS) is proposed for reducing peak-to-average power ratios (PAPRs) of universal filtered multi-carriers (UFMCs). First, we analyze the differences in PAPR between a UFMC system and an orthogonal frequency division multiplexing system.

A Novel Hybrid CFO Estimation Scheme for UFMC-Based Systems
IEEE Communications Letters, 2017In this letter, a robust hybrid carrier frequency offset (CFO) estimation scheme based on training symbols is devised for universal-filtered multi-carrier (UFMC) based systems. In this scheme, the CFO estimator based on a least square (LS) criterion is first derived to acquire a coarse frequency offset estimation with the use of a large frequency ...

Overlay Cognitive Radio Based on UFMC System
2019 6th International Conference on Electrical and Electronics Engineering (ICEEE), 2019In this paper, we consider an overlay cognitive radio (CR) consisting of a primary macro-cell and cognitive small cells of cooperative secondary base stations (SBS). We suggest studying a CR where an orthogonal frequency division multiplexing (OFDM) is used for the primary users (PU) whereas the secondary users (SU) are based on universal filtered ...

Asynchronous Multi-User Uplink Transmissions for 5G with UFMC Waveform
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017Universal filtered multi-carrier (UFMC) has been widely researched for 5G communication systems. In this paper, we propose a new UFMC receiver model and signaling structure to support asynchronous transmissions. Since the UFMC transmitter contains sub-band filters, we adopt equivalent filters at the receiver to separate target user signal over ...
