M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.

基于matlab 的动力学工具箱 做多体或机器人方向的可以看看(SPACELIB is a software library useful for the realization of programs for the kinematic and dynamic analysis of systems of rigid bodies. This library is currently used in ROBOTICS and BIOMECHANICS. It has been developed at the Mechanical Engineering Department of the University of Brescia)

截取一段音频信号作为输入信号，分别通过低通，高通和带通滤波器，比较滤波效果。(Interception of an audio signal as an input signal, respectively, through a low pass, high pass and band-pass filter, compare filtering effect.)

此文档介绍了Matlab软件的更重要的另外一种算法--插值与拟合。(This document describes the Matlab software more importantly, another algorithm- interpolation and fitting.)

三阶内模控制程序，对大滞后系统有很好的控制效果(Third-order internal model control procedures on the large time delay system has a good control effect)

it is program in matlab to solve branch equation

说明：  ldpc码在cdma中应用，matlab实现(cdma ldpc code in the application and realization of Matlab)

能够对所俩种采集的数据，把他们精确的区分开(Can to two of the data collected, and their precise separate)
