Evaluation of 5G Modulation Candidates WCP-COQAM, GFDM-OQAM, and FBMC-OQAM in Low-Band Highly Dispersive Wireless Channels

Figure 9

Overlapping between adjacent WCP-COQAM blocks and CP extension’s structure. Only GI1 and GI1′ remain equal in order to emulate a circular convolution with the channel and perform frequency domain equalization, so GI2 implies an overload that affects SE.
