Abstract

Forthcoming fifth generation (5G) mobile networks need to support a wide variety of services, from mobile broadband (MBB) communications supporting up to 100 Gbps throughput and millisecond class latency to ultra-low power machine-To-machine (M2M) communications supporting very low bit rates and tens of years operation with single battery or operation together with new energy harvesting solutions. In this paper, we concentrate on the MBB aspect and consider two new OQAM-OFDM based waveform candidates proposed for 5G communications while noting the strict time latency requirements. Also, we compare different preamble designs used for channel estimation and show that some of the pseudo-pilot power maximizing interference approximation method based preamble designs are not suitable for communications with any nonlinear power amplifier (PA) model and that an ad-hoc random OQAM based preamble design performs well compared to specific optimized preamble designs.
