捷联惯导 GPS测向wuxiangdiancexiang
尽管现在捷联惯导 GPS测向 应用很广泛 测量精度很精确 但不可避免都有自身的缺点，因此再次讨论常规无线电测向测姿问题(Although SINS application of GPS measurements to a wide range of measurement accuracy is very precise but inevitably has its own shortcomings, so once again the discussion of conventional radio direction finder to the attitude determination problem)

一种基于高阶累积量的数字调相信号识别方法
说明： 对当前通信信号中常用的数字调相信号BPSK、QPSK、1／4一QPSK、8PSK的调制识别问题，提出了一种基于信号差分高阶累积量的识剐算法。该算法分两个层次进行调制识别，首先利用信号的四阶累积量特征对BPSK、QPSK和{1／4一QPSK、8PSK}信号进行识别，然后再利用信号差分的四阶和八阶累积量特征对1/4-QPSK、8PSK信号进行识别。从理论上分析了的该算法的有效性，并通过计算机仿真验证了算法具有良好的性能。(A recognition algorithm based on differential high-order cumulant is proposed for the modulation recognition problems of BPSK, QPSK, 1/4-QPSK and 8PSK, which are commonly used in current communication signals. The algorithm is divided into two levels for modulation recognition. Firstly, BPSK, QPSK and {1/4-QPSK, 8PSK} signals are identified by using the fourth-order cumulant characteristics of signals, and then 1/4-QPSK and 8PSK signals are identified by using the fourth-order cumulant and eighth-order cumulant characteristics of signal difference. The validity of the algorithm is analyzed theoretically, and the good performance of the algorithm is verified by computer simulation.)

function ber_ml=Alamoudi(snr,soglia)
This function simulates a Alamouti scheme. The input variables are soglia and snr.
Soglia: is the number of errors after which the iterations stop. For better results, put high value of soglia, but
the simulation is longer.
snr: the signal to noise ratio (if u don t know what is a signal to noise ratio, well, come back to your high school!).
Note: U should use this function with a main function in wich u chose different value of snr. That s because this
function work just with one value of snr.
If u have problem with this code, write me at m.allegritti@email.it.
Take care!
