For Transport operators today, making passengers and crews feel safer on urban mass transportation systems, and curbing damage to rolling-stock, are two of the main priorities. To satisfy these needs, they rely more and more on surveillance systems based on audio and video sensors which are able to detect automatically potentially dangerous situations and(More)
In this paper, we investigate the joint use of multiple description coding (MDC) and multiple-input multiple-output (MIMO) technology in the specific context of wireless embedded real time video surveillance for transportation applications. The combination of both techniques is expected to provide reliability of transmitted data and graceful degradation of(More)
Opportunistic or cognitive radio system are a key technology able to enable reconfigurability and flexibility of wireless systems in the railway domain in order to answer requirements such as system availability, robustness, and traffic heterogeneity. These technologies will allow dynamic spectrum allocation and very often spectrum reuse especially in rural(More)
