Nonlinear distortion in perpendicular magnetic recording channels is known to degrade the overall system performance. In this work, we propose two nonlinear equalizers based on neural network (NN). One involves symbol decision of received signals using a multilayer perceptronNN equalizer (MLPNNE) only, and the other includes the NN equalizer to shape received signal to a partial-response target followed...
The Total Electron Content (TEC) or satellite delay can be derived from the dual-frequency of Global Positioning System (GPS). The error of TEC accuracy suffers seriously from the GPS instrumental biases, including satellite bias and receiver bias. In this paper, we apply the singular value decomposition (SVD) to derive TEC, GPS satellite and receiver biases from the 11 GPS receiver stations in Thailand,...
