无线传感网中分布式LEACH路由协议Lower Energy Adaptive Clustering Hierarchy(wsn LEACH routing protocol)

蚁群算法和遗传算法相融合，将遗传算法和蚁群算法相结合，在寻优过程中发挥各自的优势，克服各自的不足。(Ant colony algorithm and genetic algorithm integration, the genetic algorithm and ant colony algorithm combined to play their respective advantages in the optimization process, to overcome their deficiencies.)

本PPT重点解析了MATLAB中的simulink的实际应用基础步骤和方法(The the PPT focus parse in MATLAB simulink the practical application of basic steps and methods)

说明：  实际的数值是带有符号的，即可能是正数，也可能是负数，数值的正负之分如何实现？ 通过补码表示，且用一位符号位区别其正负即可。 而数值本身可以包括整数，也可以包括小数。那么，在计算机中是如何确定小数点的位置呢？ (The actual value is unsigned, which may be positive, it may be negative, positive and negative values divided how? By complement representation, and with a bit different from the positive and negative signs can be. The value itself can include an integer, it can also include decimals. Then, the computer is how to determine the decimal place?)

（7，4）系统循环码编码器 code_out = cyclic_coder(code_in) 该系统循环码编码器的生成多项式是g(x) = x^3 + x + 1 输入参数code_in是信息码字，是1×4的行向量；输出code_out是编码后的系统 循环码字，是1×7的行向量。 函数运行时，同时画出输入信息码字和循环码字的波形图。( (7,4) cyclic code system Encoder code_out = cyclic_coder (code_in) cyclic code encoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 of information input parameters code_in code word is 1 × 4 row vector output code_out System is encoded codeword cycle, the row is 1 × 7 vector. Function to run at the same time draw the input code word and code word cycle waveform.)

这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)

用matlab实现牛顿向前插值，代码简单易懂，适合初级matlab学习者。(Newton forward interpolation using matlab implementation, code easy to understand, matlab for elementary learners.)
