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

Figure 4

Basic representation of a FBMC-OQAM transmultiplexer. This scheme shows the basic idea behind FBMC-OQAM, where each symbol of each subchannel is modulated as OQAM, multiplied by its corresponding subcarrier, and filtered by the prototype filter. In the receiver, the inverse process is performed.
