Filter Bank Multicarrier Modulation: A Waveform Candidate for 5G and Beyond

Figure 10

Grid of points at which the constraints (24) should be imposed. The red disks indicate the points at which the constraints (24) are imposed. The green disks follow the red ones, thanks to symmetric and isotropic property of the design. The rest of the points (white disks) satisfy the constraints within a good approximation, since the construction is based on exponentially decaying pulses as increases.
