摘要
针对短波信道的特点,提出一种适合于短波电台组建无线数据传输网络的方案,该方案采用时分多址、时分双工、多进制频率键控调制的方式和非相干解调的方法.根据此方案设计了基于DSP芯片的系统硬件和软件,论述了软、硬件设计中的关键技术.实验测试表明,组建的网络收发数据准确高效,工作稳定可靠.
The design of a wireless data transmission network using shortwave radios is proposed based on the analysis of the shortwave channel and shortwave radio. The method of TDMA, TDD and MFSK are included. DSP chip is used in the design of hardware and software. Some key technologies of the design are described. Experiments show that this network can work steadily, transmit and receive data accurately.
