Despite of the ultra-wideband (UWB) system's robustness against multipath in cluttered environments, a number of challenges remain before UWB localization can be implemented. In particular, non-line-of-sight (NLOS) propagation is especially critical for high-resolution localization systems because non-negligibly positive biases will be introduced in distance measurements, thus degrading the localization...
Motivated by reduction of computational complexity, this work develops a pipelined adaptive filter architecture using the sign-error least mean square (SELMS) algorithm. The proposed algorithm was implemented with less than half the amount of calculation consumed for the conventional architectures. Besides, the proposed designs derived by retiming technique and with low latency also provide a faster...
This paper presents an improved result on the problem of H∞ analysis for networked control systems (NCSs) under the event-triggered communication scheme. The contribution of this paper has two aspects: (1)an improved method is proposed to calculate the maximum allowable number of successive packet losses (MANSPL)-dMANSPL with less conservative condition;(2)then, a stability theorem is presented for...
In heterogeneous MPSoCs, memory interference between the CPU and realtime cores is a critical impediment to system performance. Previous memory schedulers adopt the classic two-tier queuing system, but unfortunately the use of two-tier queuing deteriorates the QoS of scheduling policies. In this paper, we propose the Single-Tier Virtual Queuing (STVQ) memory controller for efficacious QoS-aware scheduling...
This paper introduces a novel quality-oriented cross-layer energy-efficient data communication solution (Q-PASTE) for mobile devices, with two components at different network layers. First component, the Packet/ApplicaTion manager (PAT) is deployed at the application layer of both service gateway and client host. The gateway level PAT shapes traffic into bursts to reduce the wireless transceiver's...
Multi-Symbol Encapsulated Orthogonal Frequency Division Multiplexing (MSE-OFDM) system, in which one cyclic prefix (CP) is used for a frame of multiple OFDM symbols in the time domain, will be widely applied in future communication systems. The main purpose of the MSE-OFDM system is to enhance the bandwidth efficiency deteriorated by the CP of each OFDM symbol in relative static wireless channel environment...
This paper presents a grey predictive control method for a class of nonlinear systems with unknown input delay. By using BP neural network, the unknown input delay is identified firstly. The system output is then estimated by the grey predictive algorithm. The output feedback control is fulfilled by PID algorithm which is used to tune its three parameters. By means of combining grey predictive algorithm...
