5 Potential Waves – Which Will Carry 5G?
5G will require many fundamental changes and innovations to the overall network architecture as well as exploit new system degrees of freedom. This includes the consideration of other potential waveform candidates. Wireless Week published an article written by InterDigital’s Dr. Afshin Haghighat, senior staff engineer, that discusses potential 5G waveform candidates that can overcome limitations of the orthogonal frequency multiple access (OFDM) waveform.
The article, titled Which Wave Will 5G Ride, examines five potential waveform candidates that Afshin and his colleagues recently reviewed in this EURASIP editorial. The five waveforms? Faster-than-Nyquist, Filter Bank Multi-Carrier, Universal Filtered Mutli-Carrier, Zero-Tail DFT-s-OFDM and Generalized Frequency Divison Multiplexing. Afshin provides a brief explanation of the five waveforms along with their key benefits.
The waveform that 5G will rely on is still to be determined. However, Afshin expresses that there is one clear thing: when it comes to 5G and waveform, one size will not fit all.
