Abstract
This paper compares two different filter bank multi carrier (FBMC) modulations: a critically sampled and therefore spectral maximally efficient FBMC orthogonal quadrature amplitude modulation (OQAM) approach, as well as an over sampled (OS)-FBMC system. Under a dispersive channel, FBMC/OQAM and OS-FBMC require equalisation and timing synchronisation, which here is accomplished by a fractionally spaced equaliser updated by a concurrent constant modulus and decision-directed algorithm. Simulation demonstrate that FBMC/OQAM is more difficult to equalise particularly at lower SNR, since its additional CCI terms amplify the equalisation algorithm’s gradient noise.
