This is the OFDM-DWT mmodel for OFDM modulation and demodulation. it has DWT and IDWT models

说明：  IIR滤波器设计 在设计一个IIR数字滤波器时，我们根据指标先写出模拟滤波器的公式，然后通过一定的变换，将模拟滤波器的公式转换成数字滤波器的公式(IIR filter design in the design of an IIR digital filter, we first write the analog filter based on index formula, and then through a certain transformation, the analog filters into digital filters equation formula)

ICA的经典算法JADE，非常值得下载，其中包含各种库函数以及主函数(JADE ICA s classical algorithm)

产生升余弦滤波器的时域与频域波形，带有默认参数，滚降系数为alpha。(Time domain and frequency domain waveforms produce raised cosine filter with default parameters, roll-off factor for the Alpha.)

This code is used to get the freeman code chain of a boundary image. You can use it in image fusion,registration or else

LDPC码的C语言编译码，包含校验矩阵，备注等等(LDPC codes codec C language, including parity check matrix, notes, etc.)

audio classification using SVM for 5 classes

说明：  对OFDM和其他无线接入技术在光通信中的应用讲解的非常详细，是学习光纤无线融合的必备参考书籍。。。(OFDM for Optical Communications)

说明：  用MATLAB仿真的数字下变频程序，变频，滤波未用matlab函数，而是用代码完成，便于移到DSP或FPGA上。供参考。(Using MATLAB simulation of digital down conversion process, conversion, filtering is not used matlab functions, but with code completion, easier to move on a DSP or FPGA. For reference.)
