＜正＞ This paper deals with the controller design of a networked control system with the presence of network-induced delay and transmitted data dropout. In view of data loss and network-induced delay, the networked control system is modelled as a stochastic switching discrete-time linear system with delay. By means of Lyapunov method, a novel delaydependent condition for the stability of the networked control system is given. Based on this condition, the desired controller is constructed through solving a set of linear matrix inequalities. An example is presented to illustrate the effectiveness of the proposed method.

The characterization of non-stationary signal requires joint time and frequency information. However, time and frequency are a pair of non-commuting variables that cannot constitute a joint probability density in the time-frequency plane. The time-frequency distributions have difficult interpretation problems arising from negative and complex values or spurious components. In this paper, we get time-frequency information from the marginal distributions in rotated directions in the time-frequency plane. The rigorous probability interpretation of the marginal distributions is without any ambiguities. This time-frequency transformation is similar to the computerized axial tomography (CT or CAT) and is applied to signal analysis and signal detection and reveals a lot of advantages especially in the signal detection of the low signal/noise (S/N).

Software Radio is a kind of promising technology in today and future’s communication systems. To share the resources of software radio systems to a large extent, we need to connect the instruments through backbone networks, such as the Multi-Service Transport Platform (MSTP), which is a dominating network technology that adopts both telecom and datacom traffic into existing transport infrastructures — Synchronous Digital Hierarchy (SDH). Virtual concatenation (VCAT) is one of the key technologies in MSTP. Compared with traditional contiguous concatenation, VCAT reduces transmission granularities, provides more flexibility to Network Management System (NMS) and as a result, improves the network efficiency greatly. In this paper, we introduce our design and implementation of VCAT module for a MSTP ASIC. The procedure of theoretical analysis to determine several important performance related parameters is also discussed in detail. The over- all design has been thoroughly simulated and verified through our self-made FPGA board, and has been successfully applied in our MSTP ASICs. We believe our work is significant for future development of software radio technology.

作者： Zhu Dazhong( institute of Power Devices, department of Information and {2. Engineering, Zhejiang University, {3. 3.002.)

The device structure and technical processings of quasi-planar self-aligned silicon avalanche electron emission array arc introduced. The processing step at the edge of electron emission region is about 10nm only and the width of self-aligned current channel of shallow As implantation is about 3.m. Its I-V characteristics show a larger linear region and lower series resistance than that of the previous silicon avalanche electron emission devices. Some of the electron emission characteristics are also discussed in this paper.
