An electronic device includes processing circuitry configured to calculate an intra metric based on cross correlation of first reference signal symbols (RSs) included in a first precoding resource block group (PRG) to which a target resource element (RE) belongs, calculate an inter metric based on cross correlation of one or more second RSs and one or more among the first RSs, the one or more second RSs being included in a second PRG adjacent to the first PRG along a frequency axis of a physical channel, the one or more second RSs being in proximity to the target RE, and the physical channel being received from a base station, compare a first ratio between the intra metric and the inter metric with a threshold ratio to obtain a comparison result, and determine a channel estimation mode with respect to the target RE based on the comparison result.

Electronic device performing precoding detection for adaptive channel estimation and operating method thereof

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.
