Discussing Potential 5G Waveform Candidates

With the launch of LTE/LTE-Advanced networks worldwide and the exponential increase in mobile broadband data consumption, network operators are forced to find additional ways to increase overall system capacity. The 5^th Generation of Mobile Communication, or 5G, is extensively discussed in the wireless industry and is required to support enhanced mobile broadband, massive machine type communication, and ultra-reliable and low latency communication. For this purpose, worldwide research and pre-development is being conducted, which includes the analysis of waveforms and access principles that are the basis for current LTE and LTE-Advanced networks. This application note presents potential 5G waveform candidates, discusses their advantages and disadvantages, and compares them to Orthogonal Frequency Division Multiplexing (ODFM) used in LTE/LTE-Advanced.
