Echo Cancellation Research of Channel Estimation based on PN Sequence

摘要：

For the problem of estimation sequence effect on channel estimation accuracy and echo cancellation effect, the paper, based on the basic principle of echo cancellation, analyses the effect of mechanism and its correlation of PN sequence working channel estimation on the channel estimation parameters, and compares it with the echo cancellation method which uses the input signal itself as the estimation sequence. With the input signal OFDM, the result of simulation and actual operation show that the method can effectively increase both the accuracy of channel estimation and echo cancellation effect.
