Abstract :
Researchers at the University of Calgary in Canada have experimentally demonstrated distortions arising from dual-band concurrent operation and modulator imperfections in a transmitter. To address this, they have proposed a neural network based digital pre-distortion (DPD) scheme, which will mitigate the effect of the distortions and that of the hardware imperfections in a single step. As well as improving performance, this one step solution will lead to significant savings in the necessary digital signal processing.
