Coding technique for out-of-band power reduction of multicarrier CDMA and OFDM systems
In this paper, we introduce a method for out-of-band power reduction of multicarrier (MC) communication systems. Recent years MC systems possess a dominated role in wireless access owing to the ability to achieve high data rates and simultaneously high robustness to multipath and fading. Despite all advantages, MC transmission produces an essential out-of-band (OOB) interference. The OOB radiation leads to the wastage of scarce spectral resources and severe threats to adjacent wireless channels.
