摘要
根据数字信道化接收机要求具有实时分析处理大量数据能力的特点,介绍了一种高效数字并行分析系统,即采用多相滤波技术实现信道化.此外,还把瞬时测频算法应用到该系统中,取得了很高的测频精确度.最后从数学模型上描述了整个接收机的工作流程,并在Matlab环境中对系统进行了仿真,得到了较好的仿真结果.
According to the characteristic of the digital channelized receiver, which must have the ability of processing the large number of data in real time, an efficient digital parallel analyzing system is introduced in this paper, and it adopts the multi-phase filter technology to implement channeLization. Furthermore, by applying instantaneous frequency measurement algorithm to this system, we can get high estimation accuracy. Finally, the working processing of the whole receiver is described from mathematics model, the system is simulated in Matlab environment, and better results are received.
