Abstract :
Following the synthesis and expansion of airborne devices´ functions and the requirement of miniaturization of size, the traditional analog IF signal receiving system shows large size, high power consummation and low stability. It is difficult to satisfy the requirement of modern communications. This system applies software radio design thought and implements all digital IF signal processing and 485 interface communication by VHDL in FPGA. By this way, the system enhances its reliability and realizes miniaturization, digitized and intellectualized. Except that, this system is apt to improve its function and promote its performance and provides the ability to develop its usage range.
