一个用在simlink 中用 dsp builder建立的FIR滤波器，每个波形都有波形显示，是学习DSP builder和FIR滤波器好资料。(One used in the FIR filter using dsp builder simlink established, each waveform has a waveform display, learning DSP builder and FIR filter good information.)

说明：  dsp相关的matlab程序，有很多哦， 很有用的(dsp procedures related to the Matlab, many Oh, very useful)

说明：  利用自相关函数估计基音周期，函数jiyinzhouqi，输入参数是分析语音文件名和帧移，帧移在5~10ms(use of the correlation function is estimated Pitch, jiyinzhouqi function, input parameters to analyze voice file names and frame shift, frame shift in the 5-10ms)

采用卡尔曼滤波器来对视频中的目标进行跟踪，带有一个产生视频的主函数，通过kalman滤波器实现对目标的跟踪，简单易懂(Kalman filter to track targets in the video, produced with a video of the main function, to achieve the target tracking by kalman filter, easy to understand)

线性规划通过换基运算的MATLAB算法程序，其中A为系数矩阵(Linear programming operation by changing the base of the MATLAB algorithm, where A is the coefficient matrix)

阵列信号处理里面deDOA估计算法 MUSIC，ESPRIT算法，空间平滑MUSIC，非常好的！(Array signal processing algorithms which estimate deDOA MUSIC, ESPRIT algorithm, spatial smoothing MUSIC, very good!)

说明：  常规的单载波调制技术在带宽有限的测井电缆上的低传输速率制约着成像测井技术的发展。在分析测井 电缆传输特性和 OFDM 技术原理的基础上 ,设计了一种基于 OFDM 技术的测井电缆高速数据传输系统 ,并介绍了 基于 OFDM 技术的测井电缆高速数据传输系统的参数设计和工作原理 ,给出了不同长度测井电缆上的测试结果。 电缆实测结果表明 ,在 7 000 m长的测井电缆上 ,基于OFDM 技术的测井电缆高速数据传输系统可获得900 kbit / s 以上的数据传输速率和低于 5E28 的误码率。当变压器的接入模式为 Mode2II时 ,系统最高的数据传输速率可达到 1. 1 Mbit/ s。(To solve t he low data t ransmission rate problem in t he conventional single car rier mod2 ulation met hod for logging cable and enhance t he data t ransmission rate , a new data t ransmission system with high data t ransmission rate for logging cable is propo sed , which is based on t he Or2 t hogonal Frequency Division Multiplexing (OFDM) technology. The working principle of OFDM modem and t he procedure of data t ransmission system are al so presented and lot s of test s are car2 ried out on logging cables with different lengt hs. It is verified that t he data t ransmission rate can reach 900 kbit/s on 7 000 meter s logging cable wit h bit er ror rate (BER) lower t han 5E28 , and t he maximum data t ransmission rate is 1. 1 Mbit/s under Mode2II of t he t ransformer .)

说明：  系统仿真了HSDPA中的HARQ系统，对HARQ系统的吞吐量，重传次数做了分析描述(Simulation of HSDPA in the HARQ system, the throughput of the HARQ system, the number of retransmission made analyzed and described)
