Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.

一个采用.NET SOCKET技术的在聊天室,内里有一个关键的技术可以看看.-.Net Socket technology for online chatting room,there is a important technology in it.

This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder). You should run "Simulation.m" function that include all modules.

加性高斯白噪声 AWGN(Additive White Gaussian Noise) 是最基本的噪声与干扰模型。加性噪声：叠加在信号上的一种噪声，通常记为n(t)，而且无论有无信号，噪声n(t)都是始终存在的。因此通常称它为加性噪声或者加性干扰。

用vb编写的能管理自己日程计划的程序。后台用access数据库，非常不错的。-with vb prepared to manage their own schedules procedures. Background database with access, very good.
