Property | OFDM | FBMC |
Cyclic Prefix Extension | Cyclic prefix is required in OFDM and this sacrifices the Bandwidth | Cyclic prefix not required and this conserves the bandwidth |
Sidelobes | Large and interfering sidelobes | Low sidelobes |
Synchronisation | For correct detection, multiple access interference (MAI) cancellation should be performed at the receiver | MAI is repressed due to excellent frequency localisation of the subcarriers |
Doppler Effect | Highly sensitive to carrier frequency offset | Less sensitive and hence performs significantly with the increase of the user mobility |
MIMO Systems | High flexibility while adopting MIMO techniques | Limited flexibility |
Spectrum Sensing | Degraded spectrum sensing performance due to spectral leakage problem in OFDM | High spectrum sensing resolution |
Computational Complexity | It has very low complexity | It has high complexity |
