In this paper, we present the sum-rate analysis of multiuser multiple-input multiple-output (MIMO) downlink systems with incremental beamforming (IB). We develop the analytical expressions of the ergodic sum-rate for the dual-transmit-antenna scenario. Based on the analytical results, we compare the performance of the proposed IB scheme with popular random beamforming techniques, such as random unitary...
In this paper, we present a new multiuser beamforming transmission scheme for multiuser multiple-input multiple-output (MIMO) systems. The new scheme is built upon the conventional single-user random beamforming system and to design the additional beamforming vectors in order to minimize the interuser interference. We analytically quantify the sum-rate performance of the resulting incremental beamforming...
We address the problem of real-time streaming applications scheduling on hybrid CPU/FPGA architectures. The main contribution is a two-step approach to minimize the buffer requirement for streaming applications with throughput guarantees. A novel declarative way of constraint based scheduling for real-time hybrid SW/HW systems is proposed, while the application throughput is guaranteed by periodic...
