This paper presents FPGA implementation of various V-BLAST detection algorithms which are Maximum Likelihood, Zero Forcing and Minimum Mean Squared Error. Firstly, the MIMO V-BLAST system structure, the mathematical models and a variety of receiver detection algorithms have been studied detailedly. And then we analyze the characteristic and performance of typical algorithms and focus on using the Verilog hardware description language to implement the V-BLAST system architecture and the three detection algorithms on the Xilinx's Vertex Series FPGA, which can give good performance. Ultimately, these simulation results had been compared with each other in terms of complexity and error performance.

In the field of wireless sensor network, positioning accuracy of the sensor in a network is directly related to the method for getting of or computing the data of sensor positions. An algebraic reconstruction technique based DV-Hop location algorithms is presented in order to reduce the localization error and much consume in computation of original DV-Hop localization algorithm based on the least square method principle. The analysis and simulation shows that the presented algorithm has obviously reduced the average localization error in the wireless sensor network.

Deforming bubbles under water are important phenomena that we always encounter in our daily lives. In this paper, we present a real-time bubble simulation framework based on shallow water simulation(SWS), spherical vortex and boundary element method(BEM). We first solve the shallow water equations to simulate the water volume and the free surface. We then adopt the flow field of spherical vortices to affect the bubbles' motion and interaction. BEM is later used to simulate the bubbles' deformation when they rise in water. In addition, we propose a method to simulate the splitting and merging of bubbles, as well as illustrating how to handle deformable objects of different scales in BEM.We finally report extensive results generated on a standard PC to demonstrate the algorithm's realism and performance.

In this paper, a high resolution direction of arrival (DOA) estimation algorithm is proposed that based on the usage of nonlinear function of sum and difference beam. The generalized expression of this technique for different scenarios was derived in details. Unlike the conventional high resolution algorithm such as the MVDR, the MUSIC, and the ESPRIT, the proposed algorithm keeps the high resolution ability under low Signal-to-Noise Ratio (SNR) conditions. In addition, the proposed algorithm is suitable for real-time applications in that it has low computation complexity. Simulation results verified the validity of the proposed algorithm.

Wireless sensor nodes are essential elements in wireless sensor networks. There are two important issues which need to be considered in order to build a sensor node: low power consumption and scalability. This paper proposes and presents a SoC architecture of wireless sensor node based on open source IP blocks such as OpenRISC 1200 microprocessor core and Wishbone Interconnect Matrix bus core. This hardware architecture is then verified in Altera Quartus II, and the power consumption and scalability of the hardware platform are assessed. At last, the whole system of the wireless sensor node is integrated on Altera DE2-70 FPGA board and its sensing, computation and wireless communication capabilities are verified.

For modulation recognition and demodulation of non-cooperative digital signals, the symbol rate is an unknown but important parameter. After an investigation of present methods in this active research area, this paper proposes a new symbol rate estimation algorithm, namely “MORAL”, based on Morlet wavelet transform and autocorrelation, in which the time-frequency features of Phase Shift Keying (PSK) signals are utilized. Simulation results show that, comparing with the traditional methods for symbol rate estimation, this new algorithm has higher estimation precision, is more robust against Doppler frequency spread and estimation error of carrier frequency, approaching more closely to Cramer-Rao Lower Bound (CRLB).

A novel online self-constructing fuzzy neural network is proposed for time-series prediction. The proposed approach not only speeds up the learning process but also builds a more parsimonious fuzzy neural network while comparable performance and accuracy can be achieved since the new growing criteria feature characteristics of growing and pruning. The learning scheme starts with no hidden neurons and parsimoniously generates new hidden units according to the proposed growing criteria as learning proceeds. In the parameter learning phase, all free parameters of hidden units are updated by the extended Kalman filter (EKF) method. Simulation results demonstrate that the proposed approach can provide faster learning speed and more compact network structure with comparable generalization performance and accuracy.

In this paper, an optimization algorithm of image segmentation for fingerprint identification ASIC(Application Specific Integrated Circuit) was presented. Firstly, the segmentation based on point-pixel was optimized aiming at image gradient, then the segmentation based on block-pixel was optimized for the mean and variance of image gray-scale, lastly, the second segmentation was optimized based on frequency calculation. The computation was reduced progressively by levels. It is suitable for parallel processing by less increasing the calculation. It was proved that the identification accuracy was improved, and the image of poor quality, such as black picture, was effectively segmented by experiment. This algorithm is benefit for fingerprint identification ASIC.
