Orthogonal Frequency Division Multiplexing Timing Synchronization in Multi-Band Orthogonal Frequency Division Multiplexing Ultra-Wideband Systems [PDF]
American Journal of Applied Sciences, 2010 Problem statement: MB-OFDM UWB systems have attractive features and received a great attention. It has the capability of sending/receiving data at rates in access of 100 Mbits sec-1. Owing to the sensitivity of OFDM systems to synchronization errors, a fast synchronization algorithm is required to discern for the start of OFDM symbol.

Non-Orthogonal Multicarrier Waveform for Radar With Communications Systems: 24 GHz GFDM RadCom
IEEE Access, 2019 In this paper, we propose the usage of Generalized Frequency Division Multiplexing (GFDM), a non-orthogonal multicarrier waveform for radar. We presented a novel method that cancels the effect of interference caused by the non-orthogonality of GFDM ...

Orthogonal frequency division multiplexing
, 2016 The contribution serves as a preview of the OFDM modulation signal, which is used in cellular and other wireless networks. We look closer on this problem and we are subsequently discussed general topics. That include an issue of mobile networks in their general concept and also more insight on the network 4 and 5 generations.
