After the analysis of control data type and network environment of this system, the dynamic access mode of Try-Once-Discarded, one-time abandonment MAC for real-time data is employed. In experimental analysis, the comparison between novel method and traditional method is carried on. 在分析了该系统的控制数据类型与网络环境之后,使用了实时性数据一次性丢弃的数据链路控制辅助技术&TOD(Try-Once-Discarded)动态存取方式。
In order to improve the spectrum utilization quality, the dynamic access uses unfixed spectrum allocation mode. 这种动态接入首次采用非固定频谱分配的模式,以实现提高频谱利用率的目的,而作为动态接入的前提是频谱感知,即探测到空闲信道。
