Abstract

We propose a blind selective mapping (BSLM) based peak-to-average power ratio (PAPR) reduction method and an independent component analysis (ICA) based channel equalization structure for millimeter wave (mmWave) filter bank multi-carrier (FBMC) with offset quadrature amplitude modulation (OQAM) systems. On the one hand, a new phase adjustment factor is introduced in the BSLM based PAPR reduction scheme, which is spectrum-efficient as the phase ambiguity incurred can be resolved blindly at the receiver, requiring no side information. On the other hand, we propose an ICA based blind equalization scheme with a new phase shift correction approach, which can resolve the phase ambiguity incurred by ICA equalization. Simulation results show that the proposed structure can provide bit error rate (BER) performance close to zero- forcing (ZF) equalization with perfect channel state information (CSI), and the BSLM based PAPR reduction outperforms the existing methods in the literature, while requiring no side information at the receiver.
