matlab simulink仿真ofdm(matlab)

基于matlab的温度检测系统里有1820与串口通行方法(Matlab-based detection system temperature, there are 1820 with the serial passage method)

说明：  录音程序，在matlab下运行。能录1-6秒的音频并对其进行时域和频域的分析。能保存文件(Recording procedures, run under matlab. 1-6 seconds of audio can be recorded and its time domain and frequency domain analysis. To save the file)

自由落体运动的MATLAB仿真实例，适合初学者学习(MATLAB simulation of free fall motion, suitable for beginners to learn)

The ZIP include BER Calculator , Noise Generator , Q_fn and QBEP for Ultrawide band

以ofdm作为调制方式的发送端的信道模型(To ofdm transmitter as modulation of the channel model)

Matlab simulink 通信系统建模与仿真一书中MIMO系统仿真的m源代码(mimo simulation )

有源逆变器中的LCL滤波器，无控制模块matlab仿真(LCL filter control module matlab simulation)

to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functions with the internal general functions use this code: A = int32(100*rand(8,8)) tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc tic for i = 1 : 1000 idct2(dct2(A)) end toc i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)

一个三维FDTD的计算程序，比较有用，适合初学者。(A three-dimensional FDTD calculation procedures, more useful for beginners.)
