Abstract

A non-orthogonal waveform, termed Nyquistspectrally efficient frequency division multiplexing (NyquistSEFDM), introduces benefits such as compressed bandwidth and low out-of-band power leakage, which meets two crucial requirements for future carrier aggregation (CA) or machinetype communication (MTC) applications. Both simulation and experimental results are presented in this work. A comparative simulation study of SEFDM signals is firstly presented to show the trade-offs between BER performance, bandwidth compression and suppressed out-of-band power leakage. Following modelling results, an enhanced multiuser diversity scenario was proposed to show future applications of SEFDM waveforms. Finally, an experimental testbed was designed to validate the coexistence of two signals. The impact of the newly proposed signals on existing 4 th generation (4G) signals is evaluated. Index Terms—Multicarrier, experiment, testbed, software de- fined radio, pulse shaping, spectral efficiency, carrier aggregation, OFDM, SEFDM, non-orthogonal.
