Network coding has recently attracted significant attention as its new paradigm promises to benefit various areas of communication and networks. The benefits come at a cost since encoding operations are required at intermediate nodes, and decoding operations are required at destination nodes. In some applications, the receive ends (the destinations) cannot,(More)
The performance of adaptive beamforming degrades substantially in the presence of steering vector mismatches. This degradation is especially severe in the near-field, for the 3-dimensional source location is more difficult to estimate than the 2-dimensional direction of arrival in far-field cases. As a solution, a novel approach of near-field robust(More)
⎯ A novel approach of unitarily interpolated array MVDR (UIA-MVDR) is proposed, aiming at avoiding the signal cancellation caused by broadband signal-correlated interferences. UIA-MVDR belongs to the classic approaches of spectral averaging. However, it is distinguished from the conventional interpolated array MVDR (IA-MVDR) by two points: 1) It imposes a(More)
Peer dynamics (departure or failure) in peer-to-peer (P2P) networks disrupts the downloading process to the peers. Previous works on fault resilience include peer selection and overlay topology organization. Random network coding based on the generation concept is a practical approach to implement network coding for data networks in general. If we model the(More)
