HHT变换中用于边际谱与FFT比较的一个源码。本人亲试，出的图形基本满足要求。你可以下来看看。(HHT marginal spectrum for the transformation of a source compared with the FFT. I pro-test, the graphics basically meet the requirements. You can look down.)

求系统单位节约给定相应的性能指标（超调量，峰值时间，调整时间），其中key=1表5 超调量 key=2表2 的超调量，y，t表示系统节约相应的函数值与其对应时间(Demand units to save the system give the corresponding performance indicators (overshoot, peak time, adjusting the time), where key = 1 Table 5 percent overshoot key = 2 Table 2 overshoot, y, t that the system saves the corresponding function value and its corresponding time)

附件为LTE里CRC校验的MATLAB源程序。(The CRC checkout of LTE.)

说明：  自己录制声音，然后对录制后的声音调制，然后再解调(Recording their own voices, and then, after recording the voice of the modulation, demodulation and then)

本程序按照胡广书《现代数字信号处理》书中的谱估计的内容仿真了各种经典谱估计方法以及现代谱估计方法（周期图法、BT法、welch法、自相关法、修正的协方差法、burg法），因为是课程作业，因此逻辑上写得十分简洁，适合初学者参考。(The program in accordance with the Hu-book of modern digital signal processing book spectral estimation simulation the various classical spectrum estimation methods, as well as the modern spectral estimation methods (periodogram, BT France, welch method, auto-correlation method, the modified covariance method , burg method), because the course work, so logically written very simple for beginners.)

针对目前双门限能量检测中存在的当判决统计量落在两门限之间时，需循环检测的问题，本文将介绍一种基于自适应双门限的能量检测算法。(we analyze and compare several main types of threshold in energy detection, then propose a new energy detection algorithm based on adaptive double threshold. )
