速率期望比较下的宽带频谱接入简化算法
Low-complexity broadband spectrum access algorithm under comparison of rate expectations
摘要
Abstract
To solve cognitive wireless network broadband spectrum sensing modes computationally intensive and prolonged perception problems, a rate-based cognitive wireless networks with low complexity wideband spectrum sensing algorithm has been proposed. In the broadband spectrum sensing based on set selection criteria, the expectations of the channel transfer rate are compared to determine the need to perceive the channel, in order to achieve reduced cognitive wireless network system channel secondary users perception of time and perception of the calculated amount of goals. After analysis and comparison of simulation, experiments show that the algorithm can effectively balance the secondary user system throughput maximization and the main conflicts between the interference of the user’s system.关键词
