QAM_OFDM

source code for fuzzy hmm 2-d in DIP

直接序列扩频的系统仿真，适合理解原理，很实用(Simulation of direct sequence spread spectrum system for understanding the principle, it is practical)

该程序是一纯滞后系统的大林控制算法，是一种不同于常规PID控制规律的新型算法。其控制效果大大优于普通PID控制算法。(that the procedure was a pure delay system Dalin control algorithm, Unlike a conventional PID control algorithm for the new law. Its effectiveness is significantly better than ordinary PID control algorithm.)

带通fft滤波器,简单实用，最干净的实现数据滤波；(Fft bandpass filter , simple and practical , the cleanest data filtering )

利用双线性Z变换设计巴特沃斯和切比雪夫I型IIR数字滤波器，包括低通、高通、带通、带阻四种形式。使用者只需指定通带、阻带的边缘实际频率及相应的衰减，便可输出数字滤波器 的级联形式的各子系统分子、分母的系数，并输出其幅频和相频响(Bilinear Z transform design Butterworth and Chebyshev Type I IIR digital filters, including low pass, high pass, band pass, band stop four forms. Users simply specify the passband edge frequency stopband actual and corresponding attenuation subsystems can form molecular cascade output digital filter coefficients of the denominator, and the output of its magnitude and phase frequency response)
