一个mimo天线阵列的m文件，有助于加深对mimo天线排布方案的理解，对学习mimo系统有一定的帮助。(A mimo antenna array of m files, enhance the scheme for mimo arrangement, antennas for learning mimo systems have some help.)

复调制的FFT变换，即ZOOMFFT，以及ZOOMFFT和FFT本质的注释，调试过，肯定没问题，希望对大家有帮助(FFT transform complex modulation that ZOOMFFT, as well as the nature of the comments ZOOMFFT and FFT, debug, certainly no problem, we want to help)

Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence. a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}. b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before spreading and after spreading

这是我在大学的时候老师讲信号检测与估计理论时候的第二章课件，老师讲得很好，一定对大家有帮助(This is my teacher in college, when speaking when the signal detection and estimation theory, the second chapter of courseware, the teacher explained things very well, it will surely help us)
