家庭基站中基于随机矩阵的能量动态检测频谱分配机制
Spectrum Allocation Mechanism Based on Dynamic Detection of Random Matrix Energy in Femtocell Base Station
摘要
Abstract
The coexistance of femtocell base station and the macro base station can cause mutual interfer-ence and coordination of spectrum requires signaling overhead. For the problems,a mechanism of spectral allocation based on random matrix is proposed. The mechanism applies dynamic idle spectrum points de-tection spectrum sensing techniques to femtocell base stations and macro base station coexistence networks. The femtocell base station receives signals at each frequency point within a period of time,then detects the spectrum availability dynamically by using random matrix energy and perceives the spectrum of holes in the network. Finally,the femtocell base station generates a collection of borrowable spectrum points,and se-lects the femtocell users whose quality of service request of the user service is high to borrow the collection. This method avoids using signaling to find available spectrum at the cost of complexity,thereby reducing network signaling overhead. Simulation shows that the mechanism can improve network capacity,fairness and network link efficiency.关键词
