Access control algorithmic for dynamic spectrum sharing communication system
|
Abstract:
Towards the MAC design of the dynamic sharing spectrum communication system, this paper proposed a new MAC frame structure which could be used in centralized networks. And designed a stotted ALOHA access control algorithm based the feedback competition CSI (channel state information) of access users. Then through analyzing the delay features and the stability, found a new solution to assure the system stable, which was the combination of pseudo-Bayesian algorithms and the multiple factor. Simulation demonstrates that the algorithm can accelerate the adjusting speed and acquire stable throughput on the conditions that there is distinct difference between the probability of transmitting and the real.
