Title:
A CHANNEL ESTIMATING METHOD
Document Type and Number:
WIPO Patent Application WO/2002/049301
Kind Code:
A1
Abstract:
The present invention discloses a channel estimating method using in the cellular mobile communication system, which transmits different pilot symbols having the correlation in both interference and fading in the same subframe at the transmitter side, at the receiver side, performs the difference operation on the received adjacent different pilot symbols, so as to eliminate interference and obtain the exact channel estimating value. The channel estimating method provided by the present invention can effectively eliminate the affect of the interference, give accurate channel parameter estimating value, avoid complex multi-users detection and reduce the complexity of the system.
