Armada and Garcia [3] have suggested a practical way of specifying the optimal operating point for OFDM in the presence of nonlinear amplifiers. Their heuristic approach involves setting the backoff such that the spectral regrowth shoulders are 20 db below the in-band signal level.

WebNov 9, 2016 · In this paper, we propose an algorithm to cancel the IN and NBI simultaneously for an OFDM based PLC system. The proposed method exploits the duality of the problem, where the IN is sparse in the time domain and the NBI is sparse in the frequency domain. WebThe paper develops several practical techniques for specifying the noise and linearity of components used in a ΔΣ fractional-N synthesizer. As an example, it presents a synthesizer with an in-band phase noise floor of -97 dBc/Hz@10 KHz for an RF output frequency of 2.432 GHz and a reference frequency of 16 MHz.
