This is a useful toolbox to study for SLAM with Matlab.

implementation of k means algorithm source code

16qam simulink ser mimo one of the receive chains fail, and the other receive chain is operational, then the performance loss is on the order of the diversity gain. In other words, the signal may still be detected, but with inferior quality. This is commonly referred to as soft failure. Fortunately, the new transmit diversity scheme provides the same soft failure. To

首先分析了瑞利衰落信道统计特性，并在此基础上给出了clarke模型，然后提出仿真方法，包括成形滤波法、jakes仿真模型及其多种改进方法，接着阐述了上述仿真模型的软件实现过程，并利用matlab进行了计算机仿真，然后给出衰落信号的仿真信号和分析结果，仿真结果证明了提出的仿真模型与理论曲线匹配度高，可以很好地模拟无线衰落信道(First analyze the statistical properties of the Rayleigh fading channel, and clarke model is given on this basis, and then asked the simulation methods, including the forming of the filter method, the the jakes simulation model and a variety of improvement, then described the simulation model of the software implementationprocess, and using matlab computer simulation, and then gives the simulated signals and analysis results of the fading signals, simulation results show the proposed simulation model with the theoretical curve to match high, can simulate the wireless fading channel)

qrs波算法，一个用maltab写的简单的算法。确定q,r,s的位置。(ECG SIMULATION USING MATLAB)

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 ( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal OFDM symbol Nfft = 128 points a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64 )

此程序为在MATLAB环境下编写的模糊控制模块，通过模糊判断改变ＰＩＤ控制的参数，实现模糊ＰＩＤ控制。(This program is written in the MATLAB environment, fuzzy control module to change the PID control parameters, the fuzzy PID control, fuzzy judgment.)

你也matlab实现抑制载波单边带调幅的仿真，包括输出各个节点的信号频谱图。(You can also achieve the suppression matlab simulation carrier single sideband amplitude modulation, including the output of each node signal frequency spectrum.)

Design a linear phase minimum order FIR Band Stop filter to stop the frequency band 0.45π to 0.55π with atleast 60dB attenuation at the edges. Further -3dB frequencies are required to be at 0.3π and 0.7π. 1. Plot the frequency response of the psuedo magnitude function using (a)rectangular window, (b)Hann window and (c) Hamming window. 2. Plot the frequency response for Rectangular and Hamming window for a length of 1024 to demonstrate the fact that the increase in the length, doesn t reduce undershoot and overshoot in Rectangular window.
