Abstract


The basic concepts of software radio hardware as the basic platform of wireless communication , as much personal communication function is implemented in software , wireless communications design a software to implement the physical layer connection . In this paper, based on the broadband band -pass sampling software radio architecture around its receivers involved in some of the key technology research . In this paper, based on software radio hardware platform , focusing on the wideband digital down-conversion and digital channelized receiver technology research and engineering to achieve . Combined with the difficulty of frequency hopping signal reception , based on software radio channelized receiver frequency hopping signal reception . The main work of this paper is summarized as follows: 1. Quadrature digital downconversion technology and implemented based on the basis of the principle of polyphase filter digital inverter technology , engineering quadrature digital downconversion technology . Digital AGC technology for short bursts of signals according to project requirements , and the realization of the project . ( 2 ) In order to receive full-band signal , in the classic based on the polyphase filter digital channelized receiver structure based on the needs of the project , proposed a new channelized receiver algorithms. Project implementation , this algorithm has been optimized and the implementation of the core module FFT engineering . Analysis currently used frequency hopping signal reception algorithm , given channelized receiver based on software radio the hopping signal reception program . 4 to achieve the software radio hardware processing platform , and the entire hardware circuit debugging .
