Xiyan Sun · Video Engineering · 2011
In this paper,a software radio baseband processing architecture and design of frequency offset estimation based on DSP are described.The hardware architecture of system is introduced.Then the soft architecture of the DSP is described,including the frame structure and the process of the EDMA channel interruption and the serial ports interruption.At last it focus on the theory of the frequency offset estimation and implementation method,and the test result is given.
