Abstract
This paper puts forward an echo cancellation method based on PN sequence for the problem of echo cancellation effect caused by channel estimation accuracy. The mechanism of the PN sequence in the echo cancellation is analyzed. After theoretical analysis and simulation, it shows that this method can effectively eliminate the echo interference and improve signal quality of communication.
