Method and Apparatus for Estimating Channel in Multiple-Input Multiple-Output Communication Systems Exploiting Temporal Correlations

摘要

Disclosed are a channel estimation method and apparatus therefor in a multi-antenna communication system using temporal correlation. A channel estimation method according to an embodiment of the present invention comprises the steps of quantizing a received signal received through a multiple receive antenna using an analog to digital converter; And reflecting a temporal correlation in the quantized received signal, and estimating a channel for the received signal received through the multiple receive antennas based on the received signal in which the temporal correlation is reflected.
