Efficient LLR Calculation for FBMC
IEEE Communications Letters, 2015Orthogonal frequency division multiplexing (OFDM) technology has been adopted in various communications and broadcasting systems, including LTE, WiMax, and DVB-T2. However, cyclic prefix (CP) and guard band are required to limit the inter-symbol and adjacent interference, which would cause loss of spectral efficiency. Filter bank multiple carrier (FBMC)

A comparison of OFDM, QAM-FBMC, and OQAM-FBMC waveforms subject to phase noise
2017 IEEE International Conference on Communications (ICC), 2017Frequencies above 6 GHz are being considered by mobile communication industry for the deployment of future 5G networks. However in the higher carrier frequencies, especially the millimeter-wave frequencies (above 30 GHz), there can be severe degradations in the transmitted and received signals due to Phase Noise (PN) introduced by the local oscillators.

Synchronization Method for FBMC Systems
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017This paper investigates timing and frequency synchronization applicable for filter bank multicarrier (FBMC) systems. Filtering and symbol overlap make designing a training period that has a specific block pattern quite difficult. To address this, a receiver architecture that exploits synchronization structure in a simple way is proposed.

SDMA for FBMC with block diagonalization
2013 IEEE 14th Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2013This paper deals with the design of MIMO pre-coding and decoding matrices for the filter bank multicarrier (FBMC) modulation. With the aim of increasing the system throughput we focus on the downlink of a multi-user communication system, where users share the same time slots and frequency resources.

Receivers for VBLAST FBMC-OQAM Systems
IEEE Communications Letters, 2020We consider vertical Bell laboratories layered space-time architecture for offset quadrature amplitude modulation based filter bank multicarrier (FBMC) systems, and propose two different receivers. We first investigate a low-complexity QR decomposition (QRD) based conventional minimum mean square error (MMSE) successive interference cancellation (C ...

FBMC-OQAM PAPR Reduction Schemes
2020 International Conference on Information and Communication Technology Convergence (ICTC), 2020Peak to average power ratio (PAPR) is a major problem that affects the performance of multicarrier systems. Filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is one of modulation schemes that has raised the attention of researchers given its superiority in terms of spectral efficiency. As any other multicarrier modulation

FBMC/OQAM Transceiver for Ultralarge Bandwidths
2020 IEEE 5th International Symposium on Telecommunication Technologies (ISTT), 2020We consider the problem of the downlink transceiver design when it needs to operate in an ultralarge analog bandwidth; more specifically, we propose to use the FBMC/OQAM system in a scenario where many other multicarrier transceivers are not able to operate.

FBMC/OQAM Modulators with Half Complexity
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011The Filter Bank MultiCarrier (FMBC) concept can be seen as an extension of the Orthogonal Frequency Division Multiplex (OFDM) principle. Indeed, in the case where each sub-carrier uses an Offset Quadrature Amplitude Modulation (OQAM), we get with the FBMC/OQAM system a multicarrier modulation scheme with relaxed orthogonality constraints so that ...

A cognitive overlay system based on FBMC
2017 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2017In this proposal, we provide details on our approach for the design of a cognitive overlay system which is implemented on a heterogeneous Software Defined Radio (SDR) platform consisting of an off-the-shelf consumer laptop and a USRP X310. To ensure high flexibility, spectral efficiency and low out-of-band radiation, we chose Filter Bank Multicarrier ...
