Adaptive Selection Method of Best Channel Estimation Scheme for Channel Environments and Estimation System Using the Same

摘要

A method for selecting and using a channel estimation technique most suitable for a channel environment operated among a plurality of channel estimation techniques and an estimation system using the same are disclosed. The channel estimation scheme is selected by selecting a channel estimation scheme that provides the highest performance among a plurality of candidate channel estimation schemes using a long preamble transmitted for channel estimation at the beginning of a packet, To recover the data symbol of the corresponding packet. According to this configuration, the channel estimation performance in the entire SNR region can be improved by adaptively selecting and using a channel estimation technique that provides the highest performance in the channel environment under operation.
