为sinudoidal模型的AIC阶估计.AIC信息准则即Akaike information criterion,是衡量统计模型拟合优良性的一种标准,又由于它为日本统计学家赤池弘次创立和发展的,因此又称赤池信息量准则。它建立在熵的概念基础上,可以权衡所估计模型的复杂度和此模型拟合数据的优良性。
在一般的情况下,AIC可以表示为: AIC=2k-2ln(L)
其中:k是参数的数量,L是似然函数。 假设条件是模型的误差服从独立正态分布。 让n为观察数,RSS为剩余平方和,那么AIC变为: AIC=2k+nln(RSS/n)
增加自由参数的数目提高了拟合的优良性,AIC鼓励数据拟合的优良性但是尽量避免出现过度拟合(Overfitting)的情况。所以优先考虑的模型应是AIC值最小的那一个。赤池信息准则的方法是寻找可以最好地解释数据但包含最少自由参数的模型。(AIC order estimation for sinudoidal model)

调制识别是非协作通信中的关键技术之一,在电子对抗、软件无线电等领域
应用十分广泛。该过程介于信号检测与解调之间,由于对传输信号没有过多的先
验信息以及在接收端有很多未知的参数,例如:信号功率,载波频率和相位偏移,
时间信息等,导致对调制方式的盲识别是一项很困难的任务。此外,实际中存在
多径衰落、频率选择性和时变信道等问题,使得这项任务变得更具有挑战性。
(The modulation recognition is one of the key technologies of the non-cooperative
communication, such as electronic countermeasures and software defination radio,
therefore it is such a significant discipline and orientation in the research of
communication field. Obviously, without enough knowledge in transmitter and verified
parameters about receivers, for example signal power, carrier frequency and phase offsets
and so force, it is hard to get the modulation of blind identification. What is more, for the
sake of the multipath fading, frequency-selective and time-varying channels in the real
scenarios the task is even harder.
