近几年来,随着经济的不断发展,无线电及计算机技术都得到了飞速的发展,与此同时,通信技术也不再是仅仅用来测试性能的硬件电路。数字通信信号在很多领域都有着非常广泛的应用,尤其是在军事、民用方面。因此,本文中主要对数字通信信号的自动识别和参数估计进行研究,由于目前对此的研究较为匮乏,所以希望本文可以对以后通信技术的发展起到一定的现实意义。
In recent years, as the economy continues to evolve, both radio and computer technologies have been rapidly evolving. At the same time, communication technologies are no longer just hardware circuits for testing performance. Digital communication signals have a very wide range of applications in many fields, especially in military and civilian areas. Therefore, in this paper, we mainly study the automatic identification and parameter estimation of digital communication signals. Since there is a lack of research on this issue, we hope this paper can be of practical significance for the future development of communication technologies.
