The history of the development of Chinese telemetry is introduced in the paper. The new telemetry ground station and the new onboard space telemetry system, with the idea of systematic design and the specification, are described.

To combat packet loss and realize robust video transmission over Internet and wireless networks, a new multiple description (MD) video coding method is proposed. In the method, two descriptions for each video frame is first created by group of blocks (GOB) alternation. Motion information is then dup...

This paper has proposed a fault detecting method for DC supplied permanent magnet synchronize motor (PMSM) drive systems by monitoring the drive DC input current. This method is based on the fault signal propagation from the torque disturbance on the motor shaft to the inverter input currents. The a...

Most sensors or cameras discussed in the sensor network community are usually 3D homogeneous, even though their 2D coverage areas in the ground plane are heterogeneous. Meanwhile, observed objects of camera networks are usually simplified as 2D points in previous literature. However in actual applic...

Many competing approaches exist in evaluating sensor network solutions differing by levels of ease of use, cost, control, and realism. Existing work concentrates on simulating network protocols or emulating processing units at the machine cycle level. However, little has been done to emulate the sen...
