摘要：针对已有的通信信号采集系统在复杂环境中,存在采集信息分散、信号采集规则难以确定等不足。提出了将模糊关联和信号特征提取技术相结合的通信信号采集系统设计方法。给出了系统设计完整硬件、软件设计方案。在系统软件设计中,结合复杂环境下通信信号的特点,引入模糊理论描述信号的突变性信息,采用关联规则方法,对信号的特征量数据进行模糊处理,从而实现信号特征的优劣排序。最后根据排序的结果,把数据输入到采集模块中,对不同的信号状态进行识别,实现系统复杂环境下信号采集。测试表明,这种方法能够实现复杂环境下通信信号的采集,有效地提高了信号采集的抗干扰能力,较传统采集方法有较大的优势。
In view of the existing communication signal acquisition system in complex environment, gathering information is scattered, the signal acquisition rules is difficult to determine. Fuzzy correlation and signal feature extraction technology is put forward combining the signal acquisition system design method. The complete hardware and software design of the system design scheme. In system software design, combined with the characteristics of the communication signals under complicated environment, the fuzzy theory is introduced respectively information describing the signal, by adopting the method of association rules, fuzzy characteristic of the signal data processing, so as to realize the advantages and disadvantages of signal characteristics. Finally according to the result of sorting, the input to the data acquisition module signal of different state, which can identify implementation system signal acquisition in complex environment. Tests show that this method can realize the collection of communication signals under complicated environment, effectively improve the anti-interference ability of the signal collection, than tradi- tional acquisition method has great advantage.
