Multicarrier Waveform Harmonization and Complexity Analysis for an Efficient 5G Air Interface Implementation

The coexistence of multiple air interface variants in the upcoming fifth generation (5G) wireless technology remains a matter of ongoing discussion. This paper focuses on the physical layer of the 5G air interface and provides a harmonization solution for the joint implementation of several multicar...
