Design And Implementation Of The Terminal Hardware Platform For Mobile Ad Hoc Networks

To meet the need of the pure ad-hoc mobile terminal which is the part of the 《Ad hoc Network Based on 3G》 , this paper discuss the designing and implementing the hardware platform of the pure ad-hoc mobile terminal, and also give attention to the generalized application at the same time. Firstly, the paper simply introduce the basic flow of the transmitting and receiving of the mobile terminal hardware platform. Second, the paper give out 3 different frame design scheme of the mobile terminal hardware platform, and compare the 3 design scheme and give out the final design scheme. Chapter 3 is the main part of this paper, it mainly discusses the process of the hardware platform being designed and implemented , from choosing ICs to designing the schematic of the hardware platform, and finally to the PCB board designing. In the part of choosing ICs, the scheme and characteristics of some ICs, such as DSP FPGA GPS module and A/D D/A , has been introduced. In schematic designing, an overall consideration has been described first: to divided the hardware platform into two parts, digital baseband part and analog RF part. And then 3 parts of the platform circuit have been discussed in detail: power module clock network module and analog module . In the following chapter, the interface design between the DSP and the host computer is also described in detail. Finally, the paper particularly describe the debugging of the hardware platform, some typical problem meet in the debugging is brought out and the process of the problem solving is also discussed.
