市场中现有微型无线语音传输设备一般为模拟设备,受限于调制方式其无法对语音数据进行编码或预处理,即传输设备的可用性存在一定的缺陷。针对于此,文章基于DBPSK对微型无线语音传输系统进行了研发,并开发出了系统原型样机。同模拟设备相比,其采用自定义数据帧格式进行语音数据传输,并可对数据进行编码或预处理,极大地的提高了系统的可用性。语音采集与发射采用定制芯片实现,极大的降低了发射机体积和功耗。为对研发出的系统原型机进行验证和分析,文章进行了两组测试实验。通过对测试实验数据进行分析,表明研发出的系统原型机的可用性。
The existing miniature wireless voice transmission equipment in the market is usually an analogue equipment. Due to the limitation of the modulation method, it can not encode or preprocess the voice data, that is, the availability of the transmission equipment suffers from certain defects. In response to this, the article based on DBPSK micro wireless voice transmission system has been developed and developed a prototype system prototype. Compared with the analog equipment, it adopts the custom data frame format for voice data transmission, and can encode or preprocess the data, which greatly improves the availability of the system. Voice capture and launch using a custom chip, which greatly reduces the transmitter size and power consumption. In order to validate and analyze the developed system prototype, two sets of testing experiments were carried out. By analyzing the experimental data, it shows the availability of the developed system prototype.
