—GFDM and WCP-COQAM are amongst the candidate physical layer modulation formats to be used in 5G, whose claimed lower out-of-band (OOB) emissions are important with respect to cognitive radio based dynamic spectrum access solutions. In this study, we compare OFDM, GFDM and WCP-COQAM in terms of OOB emissions in a fair manner such that their spectral(More)
—GFDM is a new modulation format whose advantages compared to OFDM reportedly make it a preferable modulation format for 5G. However, the non-orthogonal nature of GFDM with matched filtering (MF) receiver for pulses with good time-frequency localization is one of its disadvantages, leading to the proposal of WCP-COQAM, employing offset quadrature amplitude(More)
Generalized frequency division multiplexing (GFDM), windowed cyclic prefix circular offset quadra-ture amplitude modulation (WCP-COQAM) and orthogonal frequency division multiplexing (OFDM) are among the candidate 5G modulation formats. In this study, we present additional results for the OOBE comparisons between OFDM, GFDM and WCP-COQAM under equal or(More)
Multiple-input multiple output (MIMO) systems are able to serve multiple users simultaneously and using the same frequency band. Therefore, they have a quite crucial position in the design of 5G and future communication systems. However, as the number of users to be served increases, they may fail to suppress the inter-user interference adequately. It has(More)
