using fft function and other function that woring with signals, and picture in matlab

说明：  用matlab 是实现qpsk的方针算法，并计算方针和理论的符号错误率和比特错误率~~请大家指正(Qpsk with matlab is to achieve the policy algorithm, and calculate the principle and theory of symbol error rate and bit error rate ~ ~ please correct me)

程序是matlab环境下，进行方波数字信号连续，离散,多级离散等(This procedure is the Matlab environment, the square wave digital signal continuous, discrete, multi-level discrete)

matlab语言及动态环境编程经典之作，适合有一定开发经验的人员阅读。(matlab programming language and the classic dynamic environment, have some development experience for staff to read.)

此程序为测试窗函数宽度对时－频分辨率的影响，即测不准原理，对时间分辨率和频率分辨率只能取一个折中，一个提高了，另一个就必然要降低，反之亦然。(This procedure for the test window function width on- frequency resolution, that is, the uncertainty principle, the time resolution and frequency resolution can only take a compromise, an elevated, and the other is bound to reduce, and vice versa .)

this codes about design antenna dipole in MIMO.The implementation is based on the earlier implementations of WINNER II interim model [
