Multi-carrier modulation and especially CP-OFDM is widely used nowadays in several radio communications. However, FBMC is a potential alternative to CP-OFDM since it does not require cyclic prefix, and thus, it has a higher spectral efficiency. One of the characteristics of FBMC is that the received data are accompanied by a two dimensional inter-symbol interference term (2D ISI), which complicates...
In this work, we study the downlink of multiuser multiantenna systems which employ one multiple-input multiple-output (MIMO) relay and the amplify-and-forward (AF) relay strategy. We propose joint constrained optimization frameworks that consider the allocation of power levels between the base station (BS) and the relay station (RS) subject to a total power constraint and the joint design of BS precoders,...
FBMC transmission system was proposed as an alternative approach to OFDM system since it has a higher spectral efficiency. One of the characteristics of FBMC is that the demodulated transmitted symbols are accompanied by interference terms caused by the neighboring transmitted data in time and frequency domain. The presence of this interference is an issue for the Maximum Likelihood (ML) implementation...
Filter bank based multi-carrier (FBMC) is a multi-carrier modulation scheme that can be considered as an alternative to conventional OFDM with cyclic prefix (CP-OFDM) for transmission over multi-path fading channels. Compared to CP-OFDM, FBMC can provide a higher information bit rate, since it operates without the addition of a CP. Furthermore, FBMC enables the use of different pulse shapes therefore;...
In this paper we propose a novel decision feedback (DF) detection strategy for multi-input multi-output (MIMO) spatial multiplexing systems based on multiple processing branches. The proposed detection structure employs multiple cancellation branches with appropriate transformations that modify the initial design. The novel structures for detection exploit different patterns and orderings for the...
