基于Costas环的载波提取电路设计与仿真
Design and simulation of circuit for carrier extraction based on Costas loop
摘要
Abstract
Costas loop is a kind of closed-loop adaptive system which is usually used to extract coherent carrier. The paper introduces the basic principles of Costas loop in brief and aiming at the advantages of DSP development tool named as DSP Builder, designs restoring circuit for Costas loop based on FPGA by utilizing the combination method of VHDL test and Simu-link module. Finally, The correctness and feasibility of this design is verified by the simulation result.关键词
