This paper proposes a power and area efficient electrocardiogram (ECG) acquisition and signal processing application sensor node for wireless body area networks (WBAN). This sensor node can accurately record and detect the QRS peaks of ECG waveform with high-frequency noise suppression. The proposed system is implemented in 0.18- complementary metal–oxide–semiconductor technology with two...
Via the reiterative Maximum Signal Minus Interference Level (MSMIL) criterion and adaptive beamforming, a novel algorithm is proposed to suppress both the mutual interference and strong direct-path interference for shared-spectrum multistatic radar. Numerical results show advantages of the proposed method.
Local data quantization/compression is a necessity due to the bandwidth constraint of wireless sensor networks. A target tracking method that uses quantized innovations is proposed for wireless sensor networks. The posterior Cramer-Rao lower bound (PCRLB) for quantized innovations is derived. The simulation results show that the proposed method can reach the PCRLB even with the high level process...
This paper proposes a power and area efficient electrocardiogram (ECG) signal processing application specific integrated circuits (ASIC) for wireless body area networks (WBAN). This signal processing ASIC can accurately detect the QRS peak with high frequency noise suppression. The proposed ECG signal processor is implemented in 0.18μm CMOS technology. It occupies only 1.2 mm2 in area and 9μW in power...
Time synchronization is one of classical issues in network technique. It is also a hotspot to apply Network Time Protocol (NTP) to Integrated Automation System in Coal Mine. Aimed to the feature and time precision request of each level in Integrated Automation System for Coal Mine, this paper develops a time synchronization algorithm by means of Allan variance to analyze the noise in each link, in...
In this paper, a miniature low-power Electrocardiogram (ECG) signal processing application specific integrated circuit (ASIC) chip is proposed. This chip provides multiple critical functions for ECG analysis using a systematic wavelet transform algorithm and a novel SRAM-based ASIC architecture, while achieves low cost and high performance.

A fully-integrated fractional-N synthesizer (FNS) is designed and implemented, for a single-chip UHF transceiver, using 1P6M 0.18-μm RF CMOS process. The synthesizer provides very low phase-noise and extremely low reference spur RF source covering 880MHz to 1260MHz, incorporating on-chip active loop-filter and dual-stage charge-pump circuits. The measured phase-noise is -116dBc/Hz at 200KHz offset...
Greenhouse environment models easily fitted strong noise data, and its' generalization decreased. In this paper, ROLS (Regularized Orthogonal Least Squares) algorithm effectively decreased the influence of noise data, and automatically designed smaller NN structure. PSO (Particle Swarm Optimization) algorithm optimized the parameters of model. Model was experimented with spring environment data of...
