本代码是关于多天线技术空时块编码的通信系统仿真源程序，其中包括QPSK调制，QPSK解调，FFT,IFFT，STBC等模块,并给出误码率计算和性能仿真图。(The code is on the multi-antenna space-time block coding techniques of communication system simulation source code, including QPSK modulation, QPSK demodulation, FFT, IFFT, STBC and other modules, and gives the bit error rate and performance simulation map.)

this is a simple matlab program which lets you read whatever you type........ in the command window just try this and hav fun...!this is my weekend project and you surely get and excellent output from this .this program drags the excel database of speech tools and so highly efficient output can be obtained....! i have presented this simle program in my college and have won price too.....!

频域信号分析，bode图，相位图，幅频图(Frequency domain signal analysis , bode diagram, phase diagram , the amplitude-frequency diagram )

arious linear time-invariant electromagnetic systems are most conveniently analyzed in the frequency domain because there exist mature computational techniques (e.g., [1]) and related software (e.g., [2, 3]). Most measurements of antennas and microwave systems are also performed in the frequency domain (using vector network analyzers), yielding a discrete set of frequency-domain data. In order to obtain the time-domain response of such systems
