- 实现含风电场RX模型的系统潮流计算，风电场采用RX模型，此模型充分考虑风力发电机的输出功率特性，比其他模型完善，在模型中将迭代过程分为两步:常规潮流迭代计算和异步风力发电机的滑差迭代计算。- In short, the algorithm carried out to simulate the wind farmas an RX bus is as follows: 1)Begin with s=snorm in each machine, snorm being the rated s
QPSK
- this code simulate the QPSK TX and RX and plot the BER by simulations and theortically
xhmdecode
- 循环码最大的特点就是码字的循环特性，所谓循环特性是指：循环码中任一许用码组经过循环移位后，所得到的码组仍然是许用码组，也就是说，不论是左移还是右移，也不论移多少位，仍然是许用的循环码组. 译码过程 第一步：由接收码字 Rx与监督矩阵相乘得出错误图样S； 第二步：判断S是否为零。若不为零，则出错。在假定至多只有一位错的情况下，可以有效地译出相应的信息码字。 第三步：在出错的情况下，将S与标准监督矩阵对比，得出错误的比特位并进行更正得出前四位为信息码字。-Ring
