Research And Implementation Of DS/FH Key Technologies In MANETs

This paper is focus on the implementation of physical layer of MANET. At first, we present the structure and feature of MANET, summarized the function and the communication pattern of the physical layer , and then given the frame design scheme of the mobile terminal hardware platform. Secondly, the digital AGC and the radio frequency control unit is realized aimed at burst transferpattern of MANET, gave detail of its implementation on FPGA. Base on analyzing of the key technologies of the frequency-hopping communication system, designed a DS/FH hybrid spread spectrum signal source . At last, gave in detail of hardware debugging process of all the signal source modules, the results of the test showed that the signal source got the goal and worked stably.
