The strategy presented in this paper is based on modifying the past patterens and adjusting the content of the driving patterns by a new algorithm. Learning happens during the driving procedure of a mobile vehicle. The purpose of this paper is to solve the problem how to realize the hardware neurocomputer by back propagation (BP) neural network learning on-line.

In this paper a comparison of several coarse time synchronization(CTS) algorithms for OFDM is presented. The goal of a CTS is to achieve a timing estimate that avoids IST in the receiver. Five coarse timing estimation algorithms are examined and their performances are compared associated with hardware complexity. Simulations has been performed for DVB-T 2K system in thee different channels.

In this paper, we describe hardware architecture of fuzzy processors for reasoning involving fuzzy control“Heuristics”. This we believe will lead to fuzzy systems that are closer to the way humans process domain knowledge for decision making. One noticeable beneficial effect based on our notion of fuzzy heuristics is the significantly reduced number of rules required.

Lateral Information Propagation Neural Networks (LIPN) is proposed for on-line interpolation. The proposed neural network technique is the real time computation method through the inter-node diffusion. In the network, a node corresponds to a state in the quantized input space. Through several simulation experiments, real time reconstruction of the nonlinear image information is processed.

Static testing of analog-to-digital (A/D) and digital-to-analog (D/A) converters becomes more difficult when they are embedded in a system on chip. Built-in self-test (BIST) reduces the need for external support for testing. This paper proposes a new static BIST structure for testing both A/D and D/A converters. By sharing test circuitry, the proposed BIST reduces the hardware overhead. Furthermore, test time can also be reduced using the simultaneous test strategy of the proposed BIST. The proposed method can be applied in various A/D and D/A converter resolutions and analog signal swing ranges. Simulation results are presented to validate the proposed method by showing how linearity errors are detected in different situations.

In this paper, we improved the O-Ring Measurement System(O-R MS) based on oriental constitutional theory of four classes for objectify constitutional diagnosis by O-Ring test method which is one of effective methods in several constitutional diagnosis. The result of using in a half of year, some problems are pointed out. To settle these problems, we improved the actuator, display module, sensor module, and hardware of controller. Also, the software is supplemented to using the more decision parameters. It is estimated to have a high practical use for the objectified constitutional diagnosis.

현재는 IPv4의 주소 체계를 사용하여 많은 단말기들이 인터넷에 연결되고 있다. 32비트 주소 체계인 IPv4는 앞으로 유비쿼터스 환경에서 모든 단말기에 주소를 할당 할 수 없는 문제점을 가지고 있다. 이런 문제점을 해결하기 위해 새로운 주소 체계인 IPv6가 연구되고 있다. 현재의 주소 체계를 사용하고 있는 대부분의 단말기들과 IPv6의 주소 체계를 사용하는 단말기들을 직접 연결하는 것은 불가능하다. IPv4에서 IPv6의 주소 체계로 넘어가는 과도기적 단계에서 두 프로토콜 간외 상호 변환이 필요하다. 본 논문에서는 IPv4와 IPv6의 변환 기술인 SIIT(Stateless IP/ICMP Translator)를 하드웨어로 설계하기 위하여 VHDL로 모델링 하였으며 FPGA에서 검증하였다.

Control algorithm for remote transmission processing system for ECG signals is proposed. Software for the system hardware consists of system control algorithm and signal processing algorithm. Since signal processing algorithm is now under developing, this paper describes the details of system control only.
