smart.doc
- 设计一个MCS-51单片机控制的程控增益放大器的接口电路。输入信号小于10mv,要求当输入信号小于1mv时,增益为1000,而输入信号每增加1mv时,其增益自动减少一倍,直到100mv为止。(Design a MCS - 51 single chip microcomputer control the interface circuit of programmable gain amplifier.Input signal is less than 10 mv, asked when the i
LDPC_TMH_11_译码_初始化-多次迭代
- 该代码是实现LDPC编译码的C语言实现,编码采用的IRA LDPC编码算法,而译码采用的是对数域上的BP算法(LLR BP 算法),该代码先是实现了LDPC代码的编码过程,然后在通过LLR BP算法一步一步实现译码过程。译码主要过程有:初始化过程,校验节点更新过程,比特节点更新过程,最后进行译码判决,如果满足译码要求或者达到迭代最大次数则退出,否则返回到校验节点更新继续往下循环执行。(This code is to achieve the LDPC code by the C language,
