From: Spectral Efficiency Comparison of OFDM/FBMC for Uplink Cognitive Radio Networks
Experimental results of single-user resource allocation for one and multiple spectrum holes with 
= 0. 2 km: (a) Averaged spectral efficiency versus number of subcarriers for one spectrum hole case. (b) Averaged spectral efficiency versus interference level for multiple spectrum holes case. (c) (FBMC-OFDM)/OFDM versus number of subcarriers for one spectrum hole case. (d) (FBMC-OFDM)/OFDM versus interference level for multiple spectrum holes case. (e) Averaged spectral efficiency versus total power limit for one spectrum hole case (f). Averaged spectral efficiency versus total power limit for multiple spectrum holes case.
