A correlation method is proposed allowing for nonlinear penalty prediction including PMD dependency for arbitrary dispersion managed WDM systems with coherent detection. Model results are confirmed by corresponding system simulations.
Accurate prediction of signal quality is presented based on an extended semi-analytical model for coherent detection optical channels after nonlinear transmission over heterogeneous uncompensated links with consideration of modulation formats, channel count, and routing.
Collaborative spectrum sensing enables opportunistic unlicensed access to the unused portions of the licensed spectrum. In this paper, we propose an effective sensor selection scheme for collaborative spectrum sensing over shadow fading channel using SVD-QR decomposition. Since shadow fading is correlated for closely spaced sensors, it is desired to select fewer independent sensors to reduce battery...
In this paper, a statistical analysis of the peak-to-average power ratio (PAPR) of Polynomial cancellation coded OFDM (PCC-OFDM) signals is presented. PCC-OFDM has the good performance of compressing intercarrier interference (ICI) at the cost of high PAPR. The most PAPR analysis assume the subcarriers to be identically and independently distributed (i.i.d). However, the correlation between adjacent...
A new discrete array signal is proposed, which is punctured binary array pair with two-level autocorrelation (PBAPT). The spectrum characters and some combinatorial admissibility conditions for PBAPT searching are given. The research results show the fact that PBAPT extends the scope of discrete array signal and enrich the theory of punctured array pair signal.
