The focus of this paper is on the precoding and feedback strategies for a radio backhaul link between an access base station (ABS) and the hub base station (HBS) in the presence of mobile stations (MSs). In this paper it is assumed that the access and the backhaul links are simultaneous and use the same frequency band. Two feedback links are exploited at the ABS in order to optimize the communication...
In this paper we present a performance comparison between two different multi-carrier transmission techniques: OFDM, based on the FFT and cyclic prefix (CP) addition; and FBMC (FilterBank MultiCarrier), which, as indicated by its name, is based on a filterbank architecture. For both schemes, we propose a joint beamforming design to be applied in multi-input-multi-output (MIMO) systems, which requires...
A comparison between two multicarrier (MC) transmission techniques is presented: OFDM, based on cyclic prefix (CP), and FBMC, based on filterbank architecture. Multistream multiple input multiple output (MIMO) techniques that require channel state information (CSI) at the transmitter and receiver, are applied in these schemes to improve their throughput. When perfect CSI is assumed, OFDM presents...
