| 摘 要： | Mobitex网络是一个仅用于数据传输的窄带无线蜂窝网络。文章提出了适用于该网络的无线调制解调器(Modem)的设计方案,并以TI公司的TMS320C55x处理器为核心,实现了MobitexModem基带处理的前向纠错、CRC、交织、扰码的功能和数据的装帧解帧,并实现了对整个Mo-dem工作任务流程的控制。该方案硬件电路上采用集成射频电路,设计简洁、功耗低,满足了Mobitex网络的要求。

| Abstract: | Mobitex network is a narrow-band,wireless cellular network for data communication.This paper gives a design of the Mobitex Modem,which not only actualizes the function of base-band process including forward error correction,CRC,interleaving,scrambling,and assembling or splitting up the frames,but achieves the working assignment proceeding control of the Modem based on the DSP processor of TMS320C55x produced by TI company.RF integrated circuits are employed for hardware design,which makes the design simple,low power dissipation,and the requirement of the Mobitex network is satisfied. |
