Recently, road detection technique is a very important part of vision navigation, which is the key technique of intelligent vehicle guidance. The detection result is seriously affected by the quality of noise and image. Road edge detection is help to analyze the direction of the road extension and the specific location of obstacles, size and speed of obstacles in the road. In this paper, several typical...
This paper investigated the admission control problem in multi-service cellular relay system with orthogonal frequency division multiplexing access (OFDMA). Subjected to a hard constraint on the quality-of-service (QoS) requirements and the capability of relay, the admission problem could be described as the problem of maximizing the amount of subcarriers saved by relaying transmission. With further...
