Abstract: A wireless communication device and a channel estimating method thereof are provided. A wireless communication device includes an interlayer interference detector configured to receive a reference signal including a plurality of layers transmitted through a plurality of ports respectively connected to a plurality of antennas and to determine whether interlayer interference occurs based on the reference signal; and a channel estimator configured to estimate a channel matrix by executing an algorithm that is based on whether the interlayer interference occurs. The wireless communication device may decode a receive signal based on the estimated channel matrix.
