A remote user authentication scheme based on the algorithm of Awasthi and Lai is proposed. The proposed scheme uses an iris-based biometric cryptographic technique to overcome the difficulty of managing security parameters in the Awasthi and Lai scheme. By combining remote user authentication and iris-based biometric cryptography, the proposed scheme achieves the security strength of the Awasthi and Lai scheme and at the same time addresses the issue of management of secret data of that scheme.

This paper presents a distributed arithmetic (DA) for highly efficient multiplier-less FIR filter designed on FPGA. First, the theory of the distributed arithmetic is described. Furthermore, a modification of the DA based on the look up table (LUT) and filter structure to implement the high-order filter hardware-efficient on FPGA is introduced. The proposed filter has been designed and synthesized with ISE 7.1, and implemented with a 4VLX40FF668 FPGA device. Our results show that the proposed DA architecture can implement FIR filters with the smaller resource usage and similar speed in comparison to the previous DA architecture.

The cellular neural/nonlinear network (CNN) has become a new tool for image and signal processing, robotic and biological visions, and higher brain functions. Based our previous research, this paper set up two new theorems of robust designs for Dilation and Erosion CNNs processing gray-scale images, which provide parameter inequalities to determine parameter intervals for implementing prescribed image processing functions, respectively. Four numerical simulation examples for Dilation and Erosion CNNs are given to illustrate the effectiveness of our theorems.

This article introduces a cooperative diversity method, where cooperation is achieved by network coding. The improved performance of wireless cooperative diversity system offered by network coding based on turbo codes is interpret. The proposed system is structured with turbo code for the relay channel. The system with network coding and a cooperative system without network coding will be compared. The simulation results will show that such system with network coding leads to better performance on BER in the case of several scenarios. Moreover, an improved framework about network coding on relay is suggested at last.

One problem of generating a model to recognize any string is how to generate one that is generalized enough to accept strings with similar patterns and, at the same time, is specific enough to reject the non-target strings. This research focus on generating a model in the form of a state machine to recognize strings derived from the direction information of character's images. The state machine induction process has two steps. The first step is to generate the machine from the strings of each target character (positive training), and the second step is to adjust the machine to reject any other string (negative training). This state machine induction method that automatically learns from strings can be applied with other string patterns recognition apart from characters.

In this paper, we designed a photoelectric guidance system for helicopter landing and recovery. Two infrared CCD cameras were used to image the four beacons lighted by semiconductor lasers on both sides of the helicopter. The beacon position and attitude were extracted by image process and target identification. Using the dual camera photogrammetry(DCP) model established, the real-time helicopter coordinates were calculated relative to the landing point. Using the high performance DSP system, two channel of image signal were collected, detected and tracked in real time and the experimental results were displayed. The hardware-in-the-loop experiment shows that the measurement accuracy of distance can reach plusmn5 cm and the measurement accuracy of angle can reach plusmn3degin the guidance system. The errors meet the accuracy requirements of safe landing for helicopters.
