Title:
METHOD AND APPARATUS FOR CHANNEL ESTIMATION IN MULTI-PATH CHANNEL
Document Type and Number:
WIPO Patent Application WO/2012/015185
Kind Code:
A2
Abstract:
A channel estimation method in a multipath channel includes receiving a signal from a channel having multipath, obtaining information related to the number of paths and synchronization information related to each path from the received signal, estimating a channel value using the obtained inforamtion realted to number of paths and synchronization information related to each path, calculating a metric using those obtained information and an impulse response value of Square Raised Cosine (SRRC) filter, and correcting the estimated channel value using the calculated metric.
