摘要
针对电台接收信号依赖于人工值守还未实现自动化接收的问题,在软件无线电的理论基础上,提出一种电台音频采集管理系统总体技术方案,并设计了一款电台外接的电台音频处理终端,旨在电台工作时终端可以自动采集、记录、识别及回放接收到的音频信号,以提高信号接收效率。该终端由通用软件无线电模块、Morse音频信号处理模块以及语音识别模块构成,模块之间相互独立,具有一定的通用性和实用性。
Aiming at the problem that the radio receiving signal depends on manual attendance and has not yet achieved automatic reception,and based on the theory of software radio,a general technical solution for radio audio collection management system is proposed and a radio audio processing terminal external to the radio is designed.The terminal can automatically collect,record,identify,and play back received audio signals when working,therebyimproving the signal reception efficiency.The terminal consists of a general software radio module,a Morse audio signal processing module,and a speech recognition module.And these modules are independent of each other and have certain versatility and practicability.
