摘要
Abstract
In this paper a novel superimposed pilot channel estimation method is proposed, which extracts the pilot from unknown data completely according to the character that the energy of periodic sequence mainly concen- trates on a few frequency points. Based on the auto-correlation of PN sequence, the impact of noise on pilot is further reduced in time domain, which increases the accuracy of channel estimation efficiently. The extensive experiment re- sults show that proposed algorithm has the＇high bandwidth efficiency, the performance of which is superior to other existing algorithms.关键词
