Abstract Power line networks can be used to increase accessibility of broadband communication services in developing countries. Nevertheless, power line networks are affected by stochastic channel alterations triggered by load connection and disconnection, branched line lengths, branches, etc. This impairment affects the implementation of Broadband Power Line Communication (BPLC) system. This paper therefore proposes an Adaptive Decision Feedback Equalisation (ADFE) technique to overcome the stochastic channel changes in powerline communication channels. An appropriate power-line channel model is selected and channel impulse responses are obtained from the selected channel model. The impulse responses are obtained and used for simulation to analysing the the performance of ADFE technique. The ADFE is simulated and then results are analyzed through comparisons with other equalizers in order to examine its performance. Simulation results prove that the adaptive decision feedback equalizer performs better to overcome the effects of stochastic changes in power-line network compared to other techniques.

Abstract To verify the advantages of deterministic matrix applied to power line carrier communication (PLCC) based on compressed sensing (CS). This article analyzed the research status of commonly used deterministic measurement matrices, and made simulation comparison. It is found that different types of deterministic measurement matrices generated based on chaotic mapping had higher reconstruction accuracy and higher reconstruction efficiency than Gaussian random matrix. Then, according to simulation results and the characteristics of PLCC signal, the Chebyshev sparse circulant (CSC) measurement matrix was designed by combining eighth-order Chebyshev chaotic and the idea of sparse and circulant. Actual circuit measurement shows that when compression rate was 40% and 60%, the reconstruction loss of CSC is 0.72dB and 0.49dB higher than that of Chebyshev chaotic measurement matrix and Chebyshev circulate measurement matrix, respectively. Obviously, the CSC measurement matrix designed in this paper can effectively improve the reconstruction accuracy.

One of the major threats to the safe and normal operation of the power transmission lines is the external force or intrusion incurred by construction trucks. Especially for the urban area, construction of truck cranes is increasingly becoming a leading cause to the damages of power transmission lines. However, the conventional monitoring method for protecting power transmission lines is to conduct a routine inspection or patrol on the transmission line network periodically, which is time-consuming and laborious. In this paper we propose a video surveillance system for automatic tracking the dangerous strength such as construction cranes. The criterion of context formation aims to detect the jib of crane and compute its extension angle. Once the crane is parked over a certain period of time, or the jib extension angle exceeds predefined thresholds, warning messages will be sent to power line supervisors. The experiments show that the system is able to achieve automatic detection of truck cranes and protect transmission lines from their careless constructions.
