The proliferation of wireless localization technologies provides a promising future for serving human beings in indoor scenarios. Their applications include real-time tracking, activity recognition, health care, navigation, emergence detection, and target-of-interest monitoring, among others. Additionally, indoor localization technologies address the inefficiency of GPS (Global Positioning System)...
In this paper, we propose a novel Intrusion Detection System (IDS), Court-like Cluster-based IDS (CCIDS), to secure routing protocols in Mobile Ad Hoc Networks (MANETs). After the network is divided into one-hop clusters, each of these clusters performs similar functions as a court in real-life, such as accusation, investigation and defence. We show that court like IDS is effective in many aspects,...
Due to the well-separated lattice structure, the excellent time-frequency (T-F) concentration of the modulation pulses, and the under spread property of the mobile radio channels, the pulse cross-correlation matrix (PCCM) at the receiver in a properly designed hexagonal multicarrier transmission scheme essentially takes on a band-limited and sparse structure. By neglecting the almost-zero-valued entries...
In this paper we present a quantized preceding scheme for the spatial multiplexing system equipped with MMSE-SIC receiver. The preceding matrix, consisting of a beamforming matrix and a power allocation matrix, is selected to maximize the minimum post-detection SINR of the MMSE-SIC receiver. Rather than the whole beamforming matrix, the beamforming vector for each data stream is selected sequentially...
