Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

在现代信号处理中对信号进行的多种加窗操作程序，如hamming窗，hanning窗(In modern signal processing of signals, plus multi-window operation, such as the Hamming window, hanning window)

本程序主要用于利用Matlab对信号波形包络提取进行仿真实现。(This procedure used mainly for the use of Matlab to extract the signal envelope waveform simulation implementation.)

许多系统包含了流量问题。例如交通系统有车流量，金融系统有现金流，控制系统有信息流等。许多流问题主要是确定这类系统网络所能承受的最大流量以及如何达到这个最大流量。MATLAB环境下解决最大流问题(Many systems contain a flow problem. Traffic such as traffic system, the financial system has cash flow, information flow control system. Many flow problem is to determine the maximum flow of such systems and how the network can bear to achieve this maximum flow. Maximum flow problem solving MATLAB environment)
