Study for the Real-time Analysis Technologies of Broadband LargeDynamic Range Wireless Communication Signal

This paper introduces the related technologies of analyzing for wireless communication signal with 10 MHz~8 GHz input frequency, 36 MHz real-time bandwidth, and at least 100 dB dynamic range. It especially describes such key technologies as system architecture based on RF (radio frequency) -IF (intermediate frequency) direct digitization, dynamic range extension and digital compensation based on both adaptive realtime AGC (automatic gain controlling) and channel delay synchronization, programmable re-configurable DDC (digital down converter) based on the integrated function of large scale FPGA (field programmable gate array) and DSP (digital signal processor), and the baseband analysis for multimode communication signal demodulation, etc. Provided with the simulation results, the technologies mentioned above can be testified their validity
