Genetic Algorithm
简单函数优化的遗传算法程序,遗传算法从问题解的串集开始搜索,而不是从单个解开始。这是遗传算法与传统优化算法的极大区别。传统优化算法是从单个初始值迭代求最优解的;容易误入局部最优解。遗传算法从串集开始搜索,覆盖面大,利于全局择优。(A genetic algorithm program optimized by simple functions)

(On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)

(1) 数据源:随机产生752*8bit作为数据源
(2) 按照DTMB的能量扩散初始相位和生成多项式来产生伪随机数据并对原始数据源进行加扰
(3) 加扰后的数据直接进行解扰,观察误码率的值,验证加扰算法
(4) 按照DTMB标准构造BCH(1023,1013)来实现BCH(762,752)信道编码器和解码器,并观察其误码率是否为0来验证其正确性。
(5) 最后把能量扩散和BCH编码级联,接收端把BCH解码和解扰级联,观察其误码率,验证正确性。
((1) Source: randomly generated 752* 8bit as data source
(2) in accordance with the energy of the initial phase and the diffusion DTMB generator polynomial to generate a pseudo-random data and the original data source scramble
(3) the scrambled data is directly descramble, the bit error rate of the observed values, verification scrambling algorithm
(4) In accordance with DTMB standard configuration BCH (1023,1013) to achieve the BCH (762,752) channel encoder and decoder and observe its error rate is 0 to verify its correctness.
(5) Finally, the energy dispersal and BCH coding cascade, the receiving end of the BCH decoding and descrambling cascade observed error rate, to verify the correctness.)
