摘要
调制方式识别广泛应用于在军用和民用通信方面。为了能快速识别出模拟信号的调制方式,采用基于特征参数的调制方式识别方法进行讨论。通过对5种模拟调制信号识别原理的分析,从提高处理速度和减少资源消耗的角度设计了流水线结构的FPGA的实现方案。仿真测试结果表明该方案设计正确、有效合理,并且处理速度快,精度高。
Modulation recognition are widely used in military and civilian communications.In this paper,the method of identifying the modulation style based on characteristic parameter was discussed,with the purpose of quickly identifying the analogue modulation.By analyzing five kinds of analogue modulation signal recognition algorithm,this paper,from the point of view to improve processing speed and reduce resource consumption,designed a pipelined FPGA implementation structure.The simulation test results showed that the design is correct,effective and reasonable,with fast processing speed and high precision.
