Abstract
With the development of software-defined radio digital communication systems,taking the field-programmable gate array (FPGA) as the control core has become a hotspot of the study on digital communication systems.In a high precision BDPSK communication system,the traditional way of acquiring a carrier based on the Costas loop can consume a large number of resources of FPGA devices.We introduce an improved Costas loop structure which can reduce the number of multipliers and adders and improve operation speed.In this 14-bit high precision intermediate frequency transmitting-receiving system,all basic units are integrated on a single FPGA chip,which can improve the integration degree of the system and its reliability.Meanwhile,all parameters and output data width of the system are programmable,which has good application prospects.关键词
