Matlab with acoutics

fdtd 二维的MATLAB 代码，加的是MAR边界(fdtd two-dimensional MATLAB code, and added that the border MAR)

数字水印提取算法，利用离散余弦变换的（dct）算法(Digital watermark extraction algorithm using discrete cosine transform (dct) algorithm)

这个程序实现了MPEG2的视频压缩，用于Internet上视频流的处理（IP流还没有实现），程序的注释相对比较少，所以可能比较难理解些。下载后请先看说明。(This program implements MPEG2 video compression, video streaming for the Internet, the processing (IP flow has not yet achieved), program notes relatively small, it may be more difficult to understand something. Please read download instructions.)

关于遗传算法的源码，用MATLAB实现的，对初学者非常有用。(The source of genetic algorithm, using MATLAB to achieve, is very useful for beginners.)

WIMAX_WZ_withencoding:信道估计，相位噪声补偿，频偏估计，编解码都有 WIMAX_WZ_withoutencoding：在上面的工程基础上，去掉编解码部分 WIMAX_WZ_withoutprocessing：在上面的工程基础上，再去掉相位噪声补偿，频偏估计 WIMAX_WZ_withoutprocessing2：在上面的工程基础上，改用新的前导和导频联合信道估计方案,参考文档《基于802_16d标准的OFDM信道估计技术的研究与实现.kdh》 因为白噪声信道仿真只能体现QPSK调制和RS-CC编码的性能，需要仿真SNR可控的SUI信道，来估计信道均衡的性能。 在多普勒频偏fd>100Hz时，联合信道估计性能才比前导估计强，否则前导估计性能更优。对于600MHz中心频率，要求收发机相对运动速度大于180km/h，这种情况出现的概率不大(WIMAX_WZ_withencoding: channel estimation, phase noise compensation, frequency estimation, the codec has WIMAX_WZ_withoutencoding: the project on the basis of the above, remove the codec section WIMAX_WZ_withoutprocessing: the project on the basis of the above, then remove the phase noise compensation, offset estimation WIMAX_WZ_withoutprocessing2: In the project on the basis of the above, use the new leader and pilot joint channel estimation scheme, the document " Standards-based 802_16d OFDM channel estimation and implementation of technology .kdh" because white noise channel simulation only reflects the QPSK modulation and RS-CC coding performance requires simulation SNR controllable SUI channel, to estimate the performance of channel equalization. When Doppler shift fd> 100Hz, joint channel estimation performance was stronger than the leading estimate, otherwise better estimation performance leader. For 600MHz center frequency transceiver requirements relative velocity )
