ds algorithm motion estimation

To calculate the Bit Error Rate (BER)of AWGN channel for a given range of SNR in MATLAB

说明：  为了达到提升公路运输的效益，降低货运成本的目的，我们提出带时间窗的基于货物运输共享的路径优化模型(In order to improve the efficiency of highway transportation and reduce the freight cost, we propose a path optimization model based on cargo transportation sharing with time window)

扩频系统中的调频扩频程序。调频扩频信号的产生和检测(FM spread spectrum spread spectrum system procedures. FM spread spectrum signal generation and detection)

说明：  工频信号的离散matlab图形画法,其中包括程序及实验报告.(Discrete-frequency signals in matlab graphics drawing method, including the procedures and experimental report.)

基于matlab的OFDM仿真程序； 我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来.. 现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.(Based on the OFDM matlab simulation program I' ll find a lot of forums and articles OFDM code, but there are left suffering, why because most only simple mapping, IDFTDFT transformation, etc., but the main synchronization and channel estimation to no one proposed, and even do it .. and now I finally found a copy of it in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time and frequency synchronization) and channel estimation, and the estimated frequency offset a series of code.)

说明：  基于matlab中的simulink，进行16QAM的仿真搭建。包括了基带信号发生器，串/并模块，模块1，载波调制模块，高斯白噪声信道，模块2，误码率计算器等，能够较好地实现16QAM的调制解调。(Based on the Simulink of MATLAB, the simulation of 16QAM is built. It includes baseband signal generator, serial / parallel module, module 1, carrier modulation module, Gaussian white noise channel, module 2, bit error rate calculator and so on. It can achieve 16QAM modulation and demodulation well.)

本资料含有低通/高通带通等matlab程序，程序简短但经典(This information contains a low pass/high pass band-pass and so on matlab program, the program short but classic)
