5G aims to enhance mobile broadband capabilities by 2020 to support a connected society with speeds over 5Gbps and latency below 1ms. The document outlines the vision for 5G and enabling technologies being researched, such as mmWave spectrum above 10GHz, massive MIMO, beamforming, advanced modulation schemes, and a cloud-based network architecture. Key research groups around the world are exploring how these technologies can deliver 10-100x increased data rates while improving coverage, capacity, security and energy efficiency.

7. 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
