ofdm系统当中的接纳控制技术 程序当中有三种接纳控制算法的对比 都是基于ofdm系统的 (ofdm systems Admission Control technology program has three admission control algorithms are based on the contrast o fdm System)

Use of Arma in filter kalman for estimating a curve prosess

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

应用很广泛的卡尔曼滤波标准matlab程序，简单明了，适合初学者。(A wide range of standard Kalman filter matlab program, plain and simple, suitable for beginners.)

In image processing, probably the most familiar is the image brightness and contrast adjustment

power_triphaseline.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_triphaseline.rar, Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

a simple qam system used to describe a qam system with random data generator and showing also a aconstellation diagram

此程序主要是通过使用小波达到音频压缩的目的，可以比较不同的小波函数和压缩次数音频文件的差异(This process is mainly achieved through the use of wavelet purpose audio compression, you can compare different compression of the wavelet function and the difference in the number of audio files)
