The disclosure relates to a communication technique and a system for converging a fifth generation (5G) and subsequent communication system with Internet of things (IoT) technology to support a higher data transmission rate than a fourth generation (4G) system. The disclosure is applied to the intelligent service based on the 5G and subsequent communication technology and IoT-related technology. The reception device according to the disclosure receives orthogonal frequency division multiplexing (OFDM) signals through a plurality of antennas, aligns the received OFDM signals, converts at least one of the aligned reception signals into a designated symbol, estimates the data symbols of the reception signals based on the designated condition, and determines the data symbol of the reception signals by synthesizing at least one of the converted reception signals among the estimated reception signals.
