Echo Cancellation Research of Channel Estimation based on PN Sequence

By Yongqin Zhou Ming Ge Shuzhi Ji

DOI: https://doi.org/10.5815/ijieeb.2010.01.05, Pub. Date: 8 Nov. 2010

For the problem of estimation sequence effect on channel estimation accuracy and echo cancellation effect, this paper, based on the basic principle of echo cancellation, analyses the effect of PN sequence mechanism and the correlation on the channel estimation parameters. Comparing with using the input signal itself as the estimation sequence. With the input signal OFDM, the results of simulation and actual operation show that the method can increase both the accuracy of channel estimation and echo cancellation effect effectively.
