SDMA for FBMC with block diagonalization

2013 IEEE 14th Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2013
This 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, 2020
We 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), 2020
Peak 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), 2020
We 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, 2011
The 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 ...

MIMO-FBMC Receivers

2017
This chapter overviews existing work in MIMO-FBMC/OQAM channel estimation and equalization, with emphasis on the more recent developments addressing strong channel frequency selectivity. Both preamble-based and scattered pilots-based schemes for channel estimation are considered.

Waveform design for QAM-FBMC systems

2017 IEEE 18th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2017
Due to its spectral efficiency and well-localized spectrum, a quadrature amplitude modulation based filter-bank multi-carrier (QAM-FBMC) is considered as one of the candidate for 5G mobile communications. In this paper, we propose a novel waveform design for the QAM-FBMC system considering time dispersion parameter.

Capacity Analysis of FBMC-OQAM Systems

IEEE Communications Letters, 2017
This letter presents a capacity analysis of filter bank multicarrier offset quadrature amplitude modulation (FBMC-OQAM) systems. In FBMC-OQAM receivers, it is common to preserve the real part of the demodulated signal samples for information recovery. The imaginary part of these samples, which are called intrinsic interference, is simply ignored.

A cognitive overlay system based on FBMC

2017 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2017
In 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 ...

Performance of FBMC for 5G Communication

2018 3rd IEEE International Conference on Recent Trends in Electronics, Information & Communication Technology (RTEICT), 2018
In this paper, performance of 5G Filter Bank Multi-Carrier (FBMC) system that reduces the problems in 4G (OFDM) system, which uses a banks of filter instead of using the Cyclic Prefix (CPs). FBMC is a form of multicarrier modulation technique that is highly used for high date rate cellular and wireless systems.
