matlab遗传算法工具箱函数及实例讲解(matlab genetic algorithm toolbox functions and examples to explain)

MATLAB求解ODE方程，里面的WORD文档详细介绍了各文件的作用(MATLAB ODE solving equations, the WORD document which details the role of each document is also loaded.)

In this File, performance evaluation of 4-QAM system in the presence of Automatic Gain Control (AGC) errors using MATLAB Software. The system is designed, modeled and simulated using Simulink to evaluate the Bit Error Rate (BER) of the system in AWGN channel. The system doesn’t have a perfect AGC, but for comparison purposes, the perfect AGC is also included and evaluated.
