Background In order to meet the increasing demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or quasi 5G communication systems. Therefore, a 5G or quasi 5G communication system is also referred to as a "super 4G network" or a "LTE-after-system". The 5G communication system is implemented in a higher frequency (millimeter wave) band (e.g., 60GHz band) to achieve a higher data rate. In order to reduce propagation loss of radio waves and increase transmission distance, beamforming, massive Multiple-Input Multiple-Output (MIMO), full-Dimensional MIMO (FD-MIMO), array antennas, analog beamforming, massive antenna techniques are discussed in 5G communication systems. Further, in the 5G communication system, development of system network improvement is being conducted based on advanced small cells, cloud radio access networks (Radio Access Network, RAN), ultra dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, cooperative multipoint (Coordinated Multi-Points, coMP), reception-side interference cancellation, and the like. In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (Sliding Window Superposition Coding, SWSC) as advanced code modulation (Advanced Coding Modulation, ACM), and filter bank multicarrier (Filter Bank Multi Carrier, FBMC), non-orthogonal multiple access (Non-Orthogonal Multiple Access, NOMA) and sparse code multiple access (Sparse Code Multiple Access, SCMA) as advanced access techniques have been developed.
