In this paper, we concentrate on multi-target fusion and tracking problems in wireless sensor network (WSN) based on distributed clustering consensus filter. In particular, for the sake of the network lifetime and the tracking accuracy in multi-target cases, a distributed target-based clustering algorithm is proposed, which consists of the cluster member selection, the cluster head competition and...
In this paper, we propose an efficient and effective there level Design Space Exploration (DSE) method for mapping a system consisting of a number of DSP functions onto an RTL or lower level model using constraint programming methodology. The design space has three dimensions: a) function execution schedule (when the functions should execute), b) function implementation assignment (how the execution...
In this paper, we describe the procedure of the Global Interconnect and Control (GLIC) synthesis step in a system level synthesis framework to automatically generate GLIC logics from a scheduled SDF. The generated GLIC logics consist of control FSMs, interconnect and data buffers to glue existing function implementations to construct the system, which is modeled by the scheduled SDF. The experimental...
Quality of Experience (QoE) is a widely used metric reflecting the users' satisfaction of the multimedia service. This paper studies the QoE-driven resource allocation technique in the Orthogonal Frequency Division Multiplexing (OFDM) system. Different from other schemes, multiuser-multiservice scenario is taken into consideration for both power allocation and subcarrier scheduling, which is much...
We have proposed a Dynamically Reconfigurable Resource Array (DRRA), which is a Coarse Grain Reconfigurable Architecture (CGRA). In this paper, we propose a hierarchical method for compiling DSP applications in Simulink into DRRA. In this method, each function in DRRA library can be implemented in different architecture styles and also each architectural style can be implemented in varying degrees...
