Tail shortening by virtual symbols in FBMC-OQAM signals
2015 IEEE Signal Processing and Signal Processing Education Workshop (SP/SPE), 2015Filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) signaling offers almost the full spectral efficiency (one complex symbol per unit area in the time-frequency plane) for long data packets. However, because of the ramp-up and ramp-down of the waveform at the beginning and the end of each packet, its spectral efficiency can

Channel Equalization for Multi-Antenna FBMC/OQAM Receivers
IEEE Transactions on Vehicular Technology, 2011In this paper, the problem of channel equalization in filter bank multicarrier (FBMC) transmission based on the offset quadrature-amplitude modulation (OQAM) subcarrier modulation is addressed. Finite impulse response (FIR) per-subchannel equalizers are derived based on the frequency sampling (FS) approach, both for the single-input multiple-output ...

Finer SVD-Based Beamforming for FBMC/OQAM Systems
2016 IEEE Global Communications Conference (GLOBECOM), 2016The combination of singular value decomposition (SVD)-based beamforming and filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) has not been successful to date. The difficulty of this combination is that, the beamformers may change dramatically between adjacent subchannels, therefore destroy the orthogonality of FBMC/OQAM ...

On pilot-symbol aided channel estimation in FBMC-OQAM
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016Filter bank multicarrier modulation is considered as a possible candidate for 5G. In this paper, we consider pilot-symbol aided channel estimation and address the problem of canceling the imaginary interference at the pilot positions. We develop a matrix formulation for the transmission system which allows us to formulate general conditions on the ...

CFO and channel estimation for SIMO-FBMC/OQAM systems
2017 23rd Asia-Pacific Conference on Communications (APCC), 2017A training-based two-step approach which addresses carrier frequency offset (CFO) and channel frequency response (CFR) estimation in single-input multiple-output (SIMO)-filter bank multicarrier (FBMC) systems based on offset quadrature amplitude modulation (OQAM), is presented.

Weighted selective mapping algorithm for FBMC-OQAM systems
2016 International Conference on Information and Communication Technology Convergence (ICTC), 2016The FBMC-OQAM is one candidate of 5G waveforms. It has many advantages such as the improved spectral efficiency, better spectral shaping, lower inter-symbol interference and low OOB radiation. However, one significant disadvantage is a high Peak-To-Average-Power-Radio (PAPR).

An MMSE-EIC equalization for FBMC/OQAM systems
2017 Progress in Electromagnetics Research Symposium - Fall (PIERS - FALL), 2017Filter bank multicarrier/offset quadrature amplitude modulation (FBMC/OQAM) is one of a promising transmission technique of the fifth generation (5G) system. By using a pulse shape with good time frequency localization (TFL), it removes cyclic prefix (CP) to obtain a higher spectral efficiency and lower out-of band radiation compared with orthogonal ...

Prediction of spectral regrowth for FBMC-OQAM system using cumulants
2014 IEEE 10th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2014Relevance of Filter Bank Multi-Carrier (FBMC) systems along with Offset Quadrature Amplitude Modulation (OQAM) for 5G Radio Access Technology (RAT) cannot be ruled out. FBMC-OQAM modulation technique has many attractive features over OFDM that make it more appealing to be the radio waveform in 5G. However, being a multi-carrier modulation technique, it

FBMC/OQAM-related new waveform
2014This exhibition proposes to demonstrate a new waveform based on filter bank multicarrier (FBMC) modulation as one of the promising technology components enabling efficient air-interface for several new usage scenarios. This is done through a complete hardware implementation on an FPGA-based digital baseband (DBB) platform of both techniques with ...
