Turbo_code_simulation
1. 程序中Turbo译码采用了MAP,LOG-MAP,和MAX-LOG-MAP三种算法。
2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数,保存下来的目的是
加快仿真的速度,如果你所仿真的Turbo码不是程序中列出的任意一种,你可以通过函数
trellis来生成自己的相关参数。
3. 程序支持1/2和1/3两种码率的Turbo码,其中1/2码率的Turbo码通过矩阵[1 0 0 1]打
孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。
4. 程序中的信噪比表示Eb/N0,通过此参数求得N0,对发送信号进行加噪。(1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.)

statistics_lognormal
1. 608组样本,第一列数字是标号,第二列数字是出现损坏的时间,第三列表示数据有效性,为0有效
2. 损坏时间是对数正态分布的,需要拟合
3. 求均值80%置信区间
4. 成本为m,价格为s,保证盈利20%,选取保修期
5. 比较保修期和拟合数据的均值
6. 若保修期就是拟合损坏时间的均值,求出利润率
loadd.m:加载样本数据,并选取有效数据
period.m:加载成本、价格数据,计算利润和保修期的关系(1.608 groups of samples, the first number is the label, the second column number is the time to appear damage, the third list shows the validity of the data, which is 0 effective.
2. damage times are logarithmic normal distribution and need to be fitted
3. mean in 80% confidence interval
4. the cost is m, the price is s, the profit is 20%, the warranty period is selected.
5. compare the mean value of the warranty period and the fitting data
6. if the warranty period is to fit the mean damage time, the profit rate is calculated.
Loadd.m: load the sample data and select the valid data
Period.m: loading cost, price data, and calculating the relationship between profit and warranty period)

BessDerivZerosBisect2
计算了贝塞尔函数的一阶导数的零点。
更新BessDerivZerosBisect.m这些变化:
1。允许对m= 0
2。允许用户指定特定的m和k值理想。
3。允许公差输入参数
4。使用一个表的查找能为m和k的小值接近初始化
5。添加错误检查
6。计算衍生w.r.t.以X而不是w.r.t.米(虽然老方法的工作也。)(Calculates the zeros of the first derivatives of Bessel function.
Updates BessDerivZerosBisect.m with these changes:
1. Allows for m = 0
2. Allow the user to specify the particular m and k values desired.
3. Allows for a tolerance input parameter
4. Uses a table look-up to get closer initializations for small values of m and k.
5. Adds error checking
6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.))
