说明：  3GPP LTE中下行链路信道模型仿真代码(3GPP LTE downlink channel model in the simulation code)

产生一个中频正交的信号，叠加有载频信号，能提出载频并对其解调(Generate an IF quadrature signal, the carrier frequency signal is superimposed, can raise the carrier frequency and demodulating)

用于进行频率调制基于MATLAB 环境下的程序(frequency FSK modulation)

用MATLAB对OFDM系统进行了仿真分析。包括信道调制方式16QAM、快速傅立叶变换、循环前后缀及信道函数窗函数等，最后计算了系统的误码率，毕设资料，非常珍贵。( MATLAB OFDM system for the simulation. the simulation uses OFDM each function module, Including 16 channel modulation QAM, Fast Fourier Transform, revolving around prefix and channel Function window function, etc. Finally, Calculate BER for OFDM system)

FIR滤波器设计的课件，大家及时下载学习！！(FIR filter design courseware, we learn from time to download! !)

1、利用自相关法找出含有大量数据的周期信号的周期 2、利用互相关对齐含有大量数据的多路采样信号以便分析 3、使用分段平滑经过求导后的含有干扰的图像曲线(1, using the autocorrelation method contains large amounts of data to identify the period of the periodic signal 2, using the cross-correlation contains a large amount of data aligned with the sampling signal for the multiplexed analysis, the use of segmented through derivative after smoothing with interference by the image curve)

有N件物品和一个容量为V的背包。第i件物品的费用是c，价值是w。求解将哪些物品装入背包可使这些物品的费用总和不超过背包容量，且价值总和最大。(There are N items and a knapsack capacity of V' s. No. i is the cost of items c, the value of w. Solving items into the backpack which will enable the cost of these items does not exceed the sum of the capacity of backpack, and the sum of the maximum value.)

说明：  we make simulation about the complex network routing based on different situations

CDMA业务信道卷积解码实现，根据上下行信道区分生成不同码率的卷积码序列，original_sequence是原始输入序列，channel_select是信道选择参数，其中下行码率为1/2，上行信道为1/3 (CDMA business channel decoder Convolutional achieve, according to the distinction between upper and lower line to generate a different channel bit rate of the convolutional code sequence, original_sequence is the original input sequence, channel_select is channel selection parameters, which downlink bit rate of 1/2, upstream channel for the 1/3)

互信息法计算延迟时间，可带入自己数据进行计算，方便快捷(Mutual information method to calculate the delay time can be calculated into your data, convenient)
