In this work we present a per-subchannel nonlinear adaptive equalizer for a class of filter bank based multicarrier (FBMC) systems. We consider the class of exponentially modulated FBMCs with offset quadrature amplitude modulated (OQAM) input symbols. We present a fractionally spaced adaptive decision feedback equalizer (DFE) based on the least-mean-square (LMS) algorithm. The input of each equalizer...
In this work we present a per-subchannel nonlinear equalizer for a class of filter bank based multicarrier (FBMC) systems. We consider the class of exponentially modulated FBMCs with offset quadrature amplitude modulated (OQAM) input symbols. We design a fractionally spaced decision feedback equalizer (DFE) that minimizes the mean squared error (MMSE) and takes into account the inter-(sub)channel...
Filter bank based multicarrier systems (FBMC) offer a number of benefits over conventional orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP). One benefit is the improved spectral efficiency by not using a redundant CP and by having much better control of out-of-band emission. Another advantage is the ease of accommodating multiple users in an FDMA fashion especially in the...

Multicarrier systems are favored for contemporary and future, both stationary and mobile, communication systems. They promise a high bandwidth efficiency and at the same time the capability to cope with frequency selective (radio) channels. Unfortunately, the peak-to-average power ratio (PAPR) is increased at the transmitter of multicarrier systems compared to single carrier systems. Filter bank based...
Multicarrier systems, used in many of today's communications standards like 802.11b, are very prominent candidates for future mobile communication systems. Complex modulated transmultiplexer filter banks (Tzannes et al., 1994) providing improved frequency responses in comparison to orthogonal frequency division multiplex (OFDM) are proposed without a cyclic prefix. For the sake of increased bandwidth...
