COMPRESSION_NN

说明：  一个利用空时编码和训练序列进行仿真的mimo ofdm系统(A use of space-time coding sequence of simulation and training systems mimo ofdm)

可以实现FFT变化的时域图分析，可以清楚的知晓信号随时间的规律变化(Changes can achieve FFT time domain analysis, the signal can be clearly aware of the law change with time)

基于的FSK的matlab，完整的程序，有能相关的说明和注释，有需要的朋友下载吧~(Based on the matlab FSK, complete program and relevant instruction and comments, the need to download friends ~)

此程序相关卡尔曼滤波，用matlab描述了卡尔曼滤波的过程。(ocedure-related Kalman filtering, Kalman filtering with matlab describes the process.)

产生不同频率、幅度的正弦波信号，叠加后，设计低通、带通滤波器进行正弦信号的谱分析及提取。(The sine wave signals with different frequencies and amplitudes are generated. After superposition, the low-pass and bandpass filters are designed for spectrum analysis and extraction of sinusoidal signals.)

uses the forward difference method for a European call.

认知无线电频谱感知，窄带周期平稳检测算法，检测有信号的频率(Cognitive radio spectrum sensing, narrowband cyclostationary detection algorithm to detect the signal frequency)

AWGN高斯白噪声信道下的能量检测算法ROC性能曲线图。(AWGN Gaussian white noise channel the energy performance detection algorithm ROC curve.)

一般的esprit算法计算复杂度高，在计算子空间是算法比较烦，改一些矩阵算法可以减少其复杂度。(Esprit general algorithm of high computational complexity in the calculation of subspace algorithms trouble is, some matrix algorithm can be changed to reduce its complexity.)
