QPSK modulation in matlab

Voicebox is a toolbox for speech analysis and widely used in this field.

使用一般PI模型拟合非线性曲线，最小二乘法参数辨识，逆模型前馈(The general PI model is used to fit the nonlinear curve, the least square parameter identification, and the inverse model feedforward.)

说明：  遗传算法借鉴了达尔文的进化论和孟德尔的生物遗传学说，模拟大自然界生物进化 机制，是一种高效、并行、全局搜索的优化方法。它能够在搜索过程中自动获取和积累 有关搜索空间的知识，并自适应控制搜索过程以求得最优解。(Genetic algorithm draws on Darwin s theory of evolution and Mendel s biological genetics, simulation of the nature of biological evolution Mechanism, is an efficient, parallel, global search optimization method. It can be automatically acquired and accumulated during the search process Knowledge about the search space, and adaptive control of the search process in order to obtain the optimal solution.)
