alamouti Algorithm describe

用于心电信号检测，使得输出的心电信号真实准确(True and accurate ECG for ECG signal detection, making the output)

实现arnold置乱，其中利用到置乱周期，是图像置乱的不错程序。(Achieve arnold scrambling, which take advantage of scrambling cycle, the image scrambling for a good program.)

任意模式的机载双基地合成孔径雷达方位非线性变标成像算法；适合于对SAR有一定基础的研究者；包含距离走动校正，方位非线性变标；变标因子推导等(Any mode airborne bistatic synthetic aperture radar imaging algorithm standard nonlinear variable orientation suitable for SAR have some basic researchers included walking distance correction, azimuth nonlinear variable standard variable scaling factor derived etc.)

这是一个matlab与simulink模型交互的例子，希望对大家有帮助。(This is a matlab simulink model of interaction with the example, we want to help.)

伪谱法地震波数值模拟,通过伪谱法对弹性波进行正演模拟(pseudo-spectral method seismic wave simulation)

filter synthesis -parts of the program, need to be completed later

分别采用RGB模型和HIS模型对图像imageLane.bmp进行平滑和锐化，并比较两种模型处理后结果是否相同(RGB model and HIS were used to model the image imageLane.bmp for smoothing and sharpening, and compare the results of the two models are the same after)

心音信号的DCT域变换压缩编码，LLoyld最佳量化与霍夫曼编码，利用心电R波进行分帧，在不到1 左右失真度的情况下达到了6.0以上的压缩比(Heart sound signals on DCT transform coding, LLoyld optimal quantization and Huffman coding, the use of ECG R wave sub-frame, less than about 1 in the case of distortion to achieve a compression ratio of more than 6.0)

QPSK的调制；比较DQPSK和QPSK在通过加性高斯白噪声信道时的误码性能；OFDM系统(QPSK modulation more DQPSK and QPSK in additive white Gaussian noise through the channel bit error performance when OFDM system)
