Software platforms of 5G

3.3 5G

5G Systems requires both spectral efficiency and robust synchronization. Majority of candidates are multicarrier and Non-orthogonal waveforms.

The members of “filtered” OFDM designs are

• 
  FBMC: Filter Bank Multi Carrier and
  
• 
  UFMC: Universal Filtered Multi Carrier.
  

FBMC: Filter Bank Multi Carrier –

It introduces per- Sub carrier filtering to reduce the side lobes. It has couple of implementation techniques they are frequency spreading (extended IFFT/FFT) and poly-phase network (more efficient, commonly employed)

Code for FBMC:
