A new cable fault location method based on wavelet reconstruction is proposed. In this method the difference between the currents of faulty phase and sound phase under the high voltage pulse excitation is used as the measured signal and is decomposed in multi-scale by wavelet transform, then reconstructed in single scale. Comparing with traditional fault location method by travelling wave, the presented method will not be interfered by the reflected wave from the branch joint of cables or from other positions where the impedances are not matched and not be influenced by fault types, otherwise, the reflected waves can be recognized even the faulty position is near to the measuring terminal, at the same time, the influence of the wave speed uncertainty can be reduced. The correctness of the proposed method is proved by simulation results.

Express DSP compliant C55x DTMF detector software is proposed in two versions: one with a 5 ms frame size and one with a 10 ms frame size. The versions are quite similar in behavior. The version with a 10 ms frame size is faster, but the overall quality is higher in the 5 ms version, due to lower time granularity. DTMF算法for TI DSP 54X/55X

Title: File Transfer client and server Description: Send or recieve files of any size or type between you and a peer. Displays bytes sent or recieved, return values of send() and recv(), bitrate in KBytes/sec, and time remaining. SendFile and RecvFile functions can easily be added and used in your own code. I tested it ofcourse, a 73 mb self extracting rar archive from South Korea to Massachusetts at 96KB/s arrived fully operational.
