Based On 3g Technology, Mobile Self-organization A Number Of Key Technologies In The Network Physical Layer Transceiver Unit

This paper is the investigation and implementation of the baseband transmitting unit and reception unit' s some key technology of the PHY layer of MANET (Mobile Ad hoc Net) based on the 3G technology. Firstly, the paper analyzes the baseband transmitting processing technology and reception' s timing synchronization technology in burst mode in Ad hoc Net. According to transmission characteristics and technology needs of the communication system of the PHY layer of the Ad hoc network, the paper provides an hardware realization scheme, which be applicable to the baseband transmitting unit and reception unit' s synchronization search in this burst transmission mode, and focuses on the designs in FPGA circuit and implementation of project on some important module. Finally, the paper introduces lots of debugging work, including problems and solving ways in debugging, and proves the implementation scheme and circuit designs feasible in practice.
