MISO Broadcasting FBMC System for Highly Frequency Selective Channels

چکیده
Abstract—In this contribution we propose new techniques for multi-user MISO broadcasting with Filter Bank based Multicarrier (FBMC) systems. FBMC is a prominent alternative to OFDM that can achieve higher bandwidth efficiency since no cyclic prefix is required. However, when extending FBMC to a multiantenna system, approaches that are used in OFDM can not be directly applied due to its special structure and the existence of inter-carrier and inter-symbol interference. We will consider a downlink scenario for the transmission from a multi-antenna base station to several single-antenna mobile stations. To this end, a Minimum Mean Square Error (MMSE) based multi-tap precoder and equalizer will be designed. Our method is of particular interest for highly frequency selective channels.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...

Filter bank-based multicarrier (FBMC) systems based on offset quadrature amplitude modulation (FBMC/OQAM) have recently attracted increased interest (in applications including DVB-T, cognitive radio, and powerline communications) due to their enhanced flexibility, higher spectral efficiency, and better spectral containment compared to conventional OFDM. FBMC/OQAM suffers, however, from an imagi...

This paper provides solutions for per-user multistream transmissions in FBMC/OQAM based multi-user MIMO downlink systems under highly frequency selective propagation conditions. A signal-to-leakage-plus-noise-ratio (SLNR) based metric is proposed, and it is tailored for the downlink of FBMC/OQAM based multi-user MIMO settings. Then at the base station, per-subcarrier fractionally spaced multi-t...
متن کاملPreamble-based Channel Estimation in OFDM/OQAM Systems: A Review
Filter bank-based multicarrier communications (FBMC) have recently attracted increased interest in both wired (e.g., xDSL, PLC) and wireless (e.g., cognitive radio) applications, due to their enhanced flexibility, higher spectral efficiency, and better spectral containment compared to conventional OFDM. A particular type of FBMC, the so-called FBMC/OQAM or OFDM/OQAM system, consisting of pulse ...
