In the further advancements for the third generation (3G) long-term evolution (LTE) system, i.e. the LTE-Advanced system, carrier aggregation (CA) is applied to support wide system bandwidth and ensure backward compatibility. In this paper, two traffic load balance methods are proposed to improve the performance of the independent carrier scheduling (ICS) scheme in CA based LTE-Advanced system with...
In this paper, we consider energy minimization for multiprocessor system-on-a-chip (MPSoC) under lifetime reliability constraint of the system, which has become a serious concern for the industry with technology scaling. As today's complex embedded systems typically have multiple execution modes, we first identify a set of ??good?? task allocation and schedules for each execution mode in terms of...
The timetabling problem is a NP-complete problem which has been committed to finding a solution by the field of operations research and computer but has not got a good solution. The timetabling is the most important problem in the course scheduling. With the development of disciplines, the change of the size and direction of enrollment, increasing the difficulty of the Course Scheduling. This paper...
This paper considers subcarrier allocation for the multihop orthogonal frequency division multiple-access (OFDMA) broadcast networks consisting of one source, multiple destinations, and one amplify-and-forward (AF) relay. In this paper, proportional fair (PF) based subcarrier allocation is discussed to get a tradeoff between the system transmission rate and fairness. First, the problem is formulated...
This paper is concerned with the analysis and synthesis problems for linear parameter-varying (LPV) systems. An LPV system resembles a linear system that generally depends on scheduling parameters in a nonlinear fashion. Without any structural assumption on the model, Lyapunov function based analysis and synthesis approaches involve solving infinite number of linear matrix inequalities. Motivated...
Software-defined radio (SDR) is the promising technology that allows the different wireless standards easily be converged. Using general purpose processors and open-source operating systems instead of dedicated hardware and software to build up the open wireless communication system platform is very flexible and low-cost solution. In this paper, an adaptive weighted-selective (WS) scheduling scheme...
