Physical-layer Network Coding (PNC) can significantly improve the throughput of two-way relay channels. An interesting variant of PNC is Analog Network Coding (ANC). Almost all ANC schemes proposed to date, however, operate in a symbol by symbol manner (memoryless) and cannot exploit the redundant information in channel-coded packets to enhance performance.(More)
In this paper, the shape features of different material of flame and interference image in video fire detection were analyzed and compared. The area, perimeter, rotundity, solidity, extent, sharp corners, similarity and centroid displacement are selected as the candidate features. After analyzing and excluding area and perimeter as these candidate features,(More)
Interference between adjacent body area networks (BANs), leading to dramatic performance degradation of the whole system, is always an unsolved issue. In this paper, we study the interference game in which BANs adjust their resource allocation strategies to avoid putting highly interfering sensors into the same time slots. Dickhaut-Kaplan algorithm is used(More)
In this paper, the authors derive a symbol error rate expression for the M-ary TH-PPM UWB system under the interference from multiple users. Monte Carlo simulations are then used to validate the analytical solutions. Moreover, the analytical results are compared to those found by Gaussian approximation. The authors further show that compared to a binary(More)
In the field of video fire detection, traditional fire color models have the poor adaptability and week robustness to interference. As fire can be divided into fire core, inner fire and outer fire areas depending on it's temperature and color, a new fire recognition model referring to the dispersion of fire color components is proposed in this paper.
