Successive interference cancellation (SIC) has been extensively applied to estimate transmit signals in communication systems. When the channel state information (CSI) and noise statistics are imperfectly estimated, the standard SIC estimators that ignore the model mismatch may perform poorly. This paper introduces regularized SIC estimation to provide robustness against the model mismatch. Suboptimal,...
This work considers the performance of none-light-of-sight (NLOS) target localization method using a distributed receiver array. The multipath propagation is modeled with single bounce reflection from unknown random scatters. A Simultaneous Target and Multipath Positioning (STAMP) method is proposed for jointly estimating the target and scatter positions given Time-of-Arrival (TOA) observations. The...
Grade estimation is one of the most complicated aspects in mining. Its complexity originates from scientific uncertainty. In this paper, a fuzzy wavelet neural network (FWNN) is proposed for grade estimation. This fuzzy neural network uses wavelet basis function as membership function whose shape can be adjusted on line so that the networks have better learning and adaptive ability. The new FWNN method...
