Practical throughput estimation for parallel databases

Methods for estimating the performance of DBMSs can aid the design of database systems by identifying potential performance bottlenecks or by predicting the relative performance of diierent designs. Performance estimation is critical in parallel database systems with distributed memory where an eeective overall performance depends on a good choice among a wide range of ways of placing data. Thi...

Performance Evaluation of Fast Link Adaptation Algorithm for Ofdm Systems

This paper investigate link quality metrics (LQMs) based on effective signal-to-interference-and-noise ratio, and mutualinformation (MI) for the purpose of fast link adaptation in communication systems employing orthogonal frequency division multiplexing and multiple-input multiple output (MIMO) antenna technology. From these LQMs the packeterror-rate (PER) can be estimated and exploited to sel...

A Low Cost Matching Motion Estimation Sensor Based on the NIOS II Microprocessor

This work presents the implementation of a matching-based motion estimation sensor on a Field Programmable Gate Array (FPGA) and NIOS II microprocessor applying a C to Hardware (C2H) acceleration paradigm. The design, which involves several matching algorithms, is mapped using Very Large Scale Integration (VLSI) technology. These algorithms, as well as the hardware implementation, are presented...

Performance of Proportional Fair Scheduling for Downlink Non-Orthogonal Multiple Access Systems

In this paper, we present the first analytical solution for performance analysis of proportional fair scheduling (PFS) in downlink non-orthogonal multiple access (NOMA) systems. Assuming an ideal NOMA system with an arbitrary number of multiplexed users, we derive a closedform solution of the optimal power allocation for PFS and design a low-complexity algorithm for joint power allocation and u...
