In this paper, we investigate the physical layer (PHY) performance of generalized frequency division multiplexing (GFDM) for high throughput wireless communication. For comparison purposes, orthogonal frequency division multiplexing (OFDM)-based IEEE 802.11ac PHY is used as a benchmark. Harnessing the flexibility of GFDM, we propose a novel configuration, being compliant to the IEEE 802.11ac PHY for...
For a linear waveform, a finite condition number of the corresponding modulation matrix is necessary for the waveform to convey the message without ambiguity. Based on the Zak transform, this letter presents an analytical approach to compute the condition number of the modulation matrix for the multi-carrier waveform generalized frequency division multiplexing (GFDM). We further propose a filter design...
In this paper we study the achievable rate region of an FBMC based two-way decode-and-forward relaying system. Unlike a CPOFDM system, the FBMC based systems experience inter-carrier interference and inter-symbol interference especially in a highly frequency selective channel. To calculate the resulting rate region, we have to solve a joint optimization of the per-subcarrier multitap filters at the...
