卫星通信中数字调相信号调制方式识别方法研究
说明: 针对数字卫星常用的 7 种通信信号调制方式(QPSK、8PSK、16QAM、32QAM、64QAM、16APSK、32APSK),对零中心归一化瞬时幅度谱密度最大值、四次方谱、幅度、高阶累积量四种特征参数进行了分析,提出了一种联合特征参数的信号调制识别方法.(Aiming at seven communication signal modulation modes commonly used in digital satellite (QPSK, 8PSK, 16QAM, 32QAM, 64QAM, 16APSK and 32APSK), four characteristic parameters of zero-center normalized instantaneous amplitude spectral density, quadratic spectrum, amplitude and high-order cumulant are analyzed, and a signal modulation recognition method of joint characteristic parameters is proposed. Method.)

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!
