这是一个小小的屏保应用程序，不知道会有什么样的结果，我都没试过。-This is a small screensaver application procedures, do not know what kind of outcome, I have never tried.

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.

这是XILINX公司V5-665-1的例程，我试过了 好用，大家可以试试！！~-This is the XILINX" s V5-665-1 of the routines, I tried the easy to use, we can try! ! ~

FMCW技术和脉冲雷达技术是两种在高精度雷达测距中使用的技术。其基本原理为，发射波为高频连续波，其频率随时间按照三角波规律变化。雷达接收的回波的频率与发射的频率变化规律相同，都是三角波规律，只是有一个时间差，利用这个微小的时间差可计算出目标距离。
