In this paper, a novel adaptive linearly constrained minimum variance (LCMV) beam former is proposed based on frequency response constraints. With frequency response constrained optimization criteria, the new constraint vector and thus the new weight vector are designed to improve the output signal to interference plus noise ratio (SINR), compared to the conventional distortion less constraint. The proposed methods flexibly control tradeoff between the output SINR performance and signal distortion. Simulation results are presented to demonstrate that the optimized beam former has higher overall performance about the SINR performance and signal distortion.

Body area communication could be a promising solution of next generation wearable communication networks for pervasive computing. Frequency characteristic of body area communication channel based on quasi-electrostatic field was studied in this paper. From the viewpoint of relaxation time of electrostatic equilibrium in human body inductive electrification, the relationship between induced charge density and strength of external electric field was derived. Transfer function of body channel was acquired and based on which the frequency characteristic was proved to be function of dielectric constant of human body and air, as well as conductivity of human body. Experiment was conducted in the frequency range from 100 kHz to 80 MHz, test results showed consistency with theoretical analysis that body channel shows low-pass property.

Network topology measurement is the basis of network management which makes better use of Internet for people. Using Trace route tool is the traditional way to get information about the network topology. However, Trace route sends numerous packets into the network which increases the network load. In order to reduce the amount of duplicated packets, this paper presents an algorithm named BST. According to the idea of Binary Search, BST selects the last node that has been probed and probes the nodes following the selected node along the path in parallel. By comparing to some major network topology probe methods, experimental results show that BST sends fewer packets and costs less running time. The efficiency of network topology probe can be improved dramatically by the BST algorithm.

Direct Mode Operation (DMO) is an important mode of operation supported by Terrestrial Trunked Radio (TETRA) standard. However, TETRA-DMO cannot perform multi-hop communication, limiting both the coverage and the scalability of the whole network. An approach to building an ad hoc network based on TEREA DMO technology and a proactive routing protocol, Optimized Link State Routing Protocol (OLSR) is proposed. The algorithm of "DMO Multipoint Relay" (DMR) selection is also introduced. Performance analysis indicates the call setup delay of group call service can meet the requirement of TETEA.

In this paper, a multi-channel digital Stretching structure applied to image multi-ships simultaneously is proposed and which is very important for the ISAR to be used in ocean environment with intensive ships. A base band width expression of ship echoes which stands for the maximum length in radial range dimension occupied by the target being imaged is deduced. Based on the fact that ISAR emission signal band width is much wider than the base band width of the target echoes, a fast multi-phase filtering algorithm which leads to a sharply reduction of the computation load in range information processing is introduced and a matrix method of the algorithm is presented. Finally, a formula for estimating the computation load in terms of the radio of radar signal bandwidth to target's base band width is given, and the correctness of the equation is verified by an example from an actual ISAR system.

The linear constrained minimum variance(LCMV) beam former is proposed when there are main lobe interference and other interferences in adaptive beam forming. Generalized side lobe canceller is equivalent to achieve a LCMV structure with the blocking matrix, which is an important part of it. This paper propose a new dimension reduction matrix blocking theory basing on the defects of the general block. Simulation results show that the method can effectively eliminate the main lobe interference, not only reduces the amount of computation, but also has good robustness.
