摘　　要：介绍了一种高性能的利用无线话音信道(25kHz信道带宽)传输数据速率为9600/19200bit/s的无线数传机的研制。该机采用GMSK调制技术,并应用了较完善的检错纠错技术,通过编制不同的软件,可灵活地支持各种通信协议。This paper introduces the implementation of the high performance wireless data transmitter. The transmitter works in the wireless voice channel (25 kHz bandwidth), and the transmission data rate is 9 600/19 200 bit/s. The transmitter utilizes GMSK modulation technology, and the error detection and error correction are applied. By software programming, the transmitter can flexibly support different kinds of communication protocols.
