CANDIDATE WAVEFORMS & THEIR KEY FEATURES FOR 5G:

OBJECTIVE: AN EFFICIENT AIR INTERFACE THAT NO LONGER DEPENDS ON STRINGENT ORTHOGONALITY & SYNC REQUIREMENTS

● GFDM: Block based modulation approach and reduces equalization & sync issues

● UFMC: Unlike OFDM, it uses sub-band filters & not cyclic prefix● FBMC: Training sequence used for sync & channel estimation● BFDM: IT exploits bi-orthogonality, a relaxed version of orthogonality

MODULATION SCHEME: BETTER THAN OFDM


DRAWBACKS OF OFDM:

● HIGHLY SENSITIVE TOWARDS FREQ ASYNCHRONICITY

● HIGH PAPR● OFDM’s APPLICABILITY WITH mmWAVE &

REQUIRED HARDWARE IS NOT CERTAIN
