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.

Rician fading is a radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by two different paths, and at least one of the paths is changing (lengthening or shortening). Rician fading occurs when one of the paths, typically a line of sight signal, is much stronger than the others. In Rician fading, the amplitude gain is characterized by a Rician distribution.
