turbo码的matlab程序,wuyufei版的(turbo codes matlab program, wuyufei version)

Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging. results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.

matlab实现了五类灰色关联度模型的计算,考虑雨衰 阴影 和多径影响，主要是基于mtlab的程序。( matlab implements five gray correlation degree computing model, Consider shadow rain attenuation and multipath effects Mainly based on the mtlab procedures.)

基于最小二乘法和最小均方误差法的信道估计，包括详细的仿真结果，如误码率和均方误差。(Based on the least squares and minimum mean square error of channel estimation methods, including detailed simulation results, such as error rate and MSE.)

写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)

it is the algorithm for nlms for a sound wave

1 把要插值的一组数据对从Excel中导出为.txt文本文件 2 启动Matlab,并运行h.m,即可看到插值曲线.(One of a set of data to be interpolated from Excel, export to. Txt text file 2 starts Matlab, and run hm, you can see the interpolation curve.)

用matlab实现神经网络的城市交通流量预测。主要以大脑生理变化过程为基础、模仿大脑的结构和功能(Neural network using matlab implementation of the urban traffic flow prediction. Major physiological changes to brain-based process, to imitate the structure and function of the brain)

capon算法，实现波达方向估计，不需要提前估计信源数！角度分辨力较高！(the the capon algorithm, the DOA estimates that do not need to estimate the number of sources in advance! High angle resolution)
