Abstract

To emit in the TV white space (TVWS) spectrum, the regulator has requested very strict spectral masks, which can be fulfilled using a FFT-modulated filter-bank multi-carrier system (FBMC) to extract one or several TVWS channels in the 470--790MHz range. Such a system reduces the channel dispersion, but even with near-perfectly reconstructing filter bank, the need for equalisation and synchronisation remains. In this work, we propose a per-band equalisation and synchronisation approach, performed by a constant modulus algorithms running concurrently with a direction-directed adaptation process for faster convergence and reduced phase ambiguity. We compare symbol- and fractionally-spaced versions, and investigate their fixed-point implementation on an FPGA. We compare the performance of the different systems in terms of mean squared error, computational cost, and robustness towards noise.
