Strong damping and large time constant is the common characteristics of marine gravity meter, in which they suppress vertical interference in the direction of the acceleration, but also result in distortion of the low-frequent gravity anomaly signals, such as amplitude attenuation and phase lag. Based on the principle of the gravimeter and the distortion of measured signals, measured distortion signals of the gravimeter can be approximately taken as the result of gravity signal convoluted with the unknown coefficients of the low-pass filter. Then, the single-channel Buss gang method based on the Sato algorithm is analyzed and used to correct the gravity anomaly distortion signal. Theoretical analysis and the result of emulations show that the correction algorithm based on the blind deconvolution can effectively eliminate the amplitude attenuation and phase lag of the gravity signal distortion and improve the accuracy of the gravity anomaly.

In present industrial field, the high-speed data acquisition system with small size, high-accuracy and multi-gain choices is badly needed. This paper presents a realizing solution of a parallel PCI high-speed data acquisition system for universal multi-channel based on the SOPC. With this system, we can either use these 12 channels together or choose combination. Meanwhile, the gain-programmed amplifier can also be selected as well as difference or single-ended parallel input way. Also, the sampling rate of the multi-channel can reach at the same time up to 200KSa/s, and the vertical resolution of the high-accuracy PCI data acquisition module is 16bit.

A novel time-frequency domain two-dimensional MMSE channel estimation (2D-MMSE) algorithm based on separation property of mobile wireless channels is proposed in this paper in order to provide the current channel state knowledge and improve the spectral efficiency in Single Carrier Frequency Domain Equalization (SC-FDE) systems over frequency-selective channels. We use the Unique Word (UW) to be the cyclic prefix and the pilot just like IEEE802.16. The UW is not need to delete in receiver, so the overhead of system is low. The 2D-MMSE estimation is simplified as an MMSE interpolation in the frequency domain cascaded by an MMSE filter in the time domain. The SVD method is adopt to reduce the complexity and keep the estimation accuracy. We also make the noise variance estimation by UW. Finally, the simulation results show that the proposed algorithm has better performance than the LS and MMSE algorithms, and the complexity of our method is lower than traditional one-dimensional MMSE.

Considering that nonlinear systems exist non-additive correlated noises, a generalized augmented Gaussian approximation filter (GAGAF) is proposed. The proposed filter makes use of the state augmented method to overcome the limitation of traditional nonlinear filters based on additive correlated noises. Based on the proposed filter framework, a novel augmented cubature Kalman filter with non-additive correlated noises (NACKF) can be developed through utilizing the spherical-radial cubature rule to computer the multi-dimensional integrals approximately. Simulation results validate the efficiency and feasibility of the proposed filter.

In this paper, Newton-Euler method is proposed to model the dynamic model for the moving-mass attitude of hypersonic vehicle and a coupled nonlinear system is obtained by reasonable simplification. A fuzzy tree inversion model is established to realize the decoupling and linearization of the three channels. For nonlinear system inversion error caused by modeling error and uncertainty, a closed-loop controller for each linear subsystem is designed to track attitude angle. Finally, the simulation results show that the control method is effective.

Nowadays, as the various applications emerge, to address the problem of the end-to-end QoS guarantee in the heterogeneous networks is becoming more and more important. Considering the communication between two nodes within a domain or cross-domain in the heterogeneous networks, we design the scheme of Signaling of Cross-domain QoS Cooperation in heterogeneous networks (SCQC). In SCQC, the SSE nodes can quickly establish the QoS path. To provide the end-to-end communication cross domain, a QoS parameter mapping rule in heterogeneous is designed. Then, we proposed the End-to-end SLA Negotiation algorithm based on the state of the Data Stream (ESNDS), which can effectively guarantee service end-to-end QoS by dynamically adjusting the level of service in different domains according to the current state of the data stream. Through the performance analysis and simulations, we evaluate the time to establish QoS path and end-to-end latency of service with our algorithm. The results prove the effectiveness and feasibility of the ESNDS in guaranteeing the end-to-end QoS in heterogeneous networks.

Greenhouse control systems need to achieve three targets at the same time: low cost, high stability and the ability to implement complex control algorithm. Therefore, an automatic data acquisition and control system was designed based on RS-485 protocol in this paper. The system has three layers: the bottom layer consists of sensors and actuators, the middle layer is comprised of I/O nodes and the top layer is a main controller. An I/O node based on single chip microcomputer is responsible for executing commands of the main controller. The main controller based on ARM & Linux is in charge of scheduling of all commands. It controls temperature with hysteresis control algorithm. Firstly, the research status of hardware and topology structure was discussed, and their merits and drawbacks were found out. Secondly, an automatic data acquisition and control system was designed based on RS-485 protocol according to the needs of greenhouse control. Finally, the test process was analyzed and the running results were shown. This system was successfully used in our experimental greenhouse.

Deep hole diameter measurement questions are difficult at home and abroad, the current measurement method has the disadvantages of slow measuring speed and low precision. As the aperture decreasing, the measurement would be more difficult and the accuracy would be reduced. According to the above conditions, the noncontact measurement method based on the capacitance sensor is given out. The method can effectively improve the efficiency and accuracy of measurement. CCD combines with the 2-D micro-adjustment completes the function of precise positioning. Modular circuits make the signal integrity and accurate. LABVIEW software completes the function of controlling the system automatically, data acquisition and error correction. The experiments show that the scope of the whole system can be from Φ2.4mm to Φ7mm, the maximum resolution can be up to 0.5um, the highest precision can be up to 5um and linearity can be achieved 0.6018%. So the system can achieve nanometer measurement requirements.
