Research on desigin and application of CDMA 1X DTU

Along with the increasing real-time request to the communications'efficiency,especially in the process of transmission of massive data,the bandwidth of traditional data transmit unit(DTU) based on GPRS network is obviously inadequate,however the DTU based on the CDMA 1X communication net is able to solve this problem.With micro control unit(MCU)as the core,the design course of DTU is particularly demonstrated in conjunction with characteristic of MAIZ Communication network.The concrete design scheme is given.The hardware structure is built,The design flowchart and the key design points of software system are discussed.
