In orthogonal frequency division multiple access(OFDMA) based femtocell networks,the co-tier interference among femto base stations(FBS) becomes important in multiuser and densely deployed *** order to mitigate the co-tier interference and enhance the system total throughput,this paper proposed a best effort spectrum allocation scheme based on the extension of graph *** the scheme,a controller was proposed to collect the channel state information(CSI)of all femtocell user equipments(FUEs) in a certain ***,the controller evaluated the signal-to-interference Ratio(SIR) of each FUE and determined the set of its interference *** calculating the received power matrix(RPM) among FUEs and building interference graph matrix(IGM),different spectrum resource blocks(RBs) were assigned to the users with interference relation,while users without interference relation shared the same RBs,which could increase the spectrum *** results show that the proposed algorithm can significantly improve the RB usage efficiency compared with the basic graph coloring theory,and more than 80% improvement can be acquired in dense deployment ***,the throughput of both cell edge macro user equipments(MUEs) and cell edge FUEs is guaranteed on the premise of low interference.

Traditional equalization algorithms for multiple input multiple output (MIMO) systems suffer from high complexity and low convergence rate. So an improved adaptive reduced-rank joint detection algorithm of multistage Wiener filter (MSWF) based on rectangle blocking matrices is proposed. The MSWF is implemented by the correlation subtraction algorithm (CSA) structure and is called unitary multistage Wiener filter (UMSWF). The new scheme adopts rectangle submatrix as blocking matrix, which is chosen from the square blocking matrix for UMSWF. The proposed algorithm can reduce the size of the observation data vectors step by step in the forward recursion decomposition of UMSWF. Thus, the computational complexity is reduced and the convergence rate is increased. Theoretical analysis and simulation results show that this improved adaptive reduced-rank joint detection algorithm of UMSWF based on rectangle blocking matrix has better performance such as lower complexity and faster convergence rate. In particular, simulations are conducted in the verticalBell Labs layered space-time (V-BLAST) system which adopts BPSK modulation, where 4 and 8 antennas are equipped at the transmitter and receiver, respectively. Compared with traditional equalization algorithm based on UMSWF, our new method can achieve the same BER performance at high SNR with only 0.5 times that of computational complexity.

Building a tractable and annotated router-level topology models is critical for researchers to evaluate the performance of networking protocols,to assess the effectiveness of security techniques to protect the network from attacks,***,obtaining a tractable router-level topology is a difficult *** it is harder to obtain various routers’and links’annotations（*** traffics,link roles, router roles）than the routers’interconnectivity relationship. In this paper,the authors present a simple and practical method to model a tractable and annotated router-level *** mapping routers with same geolocation into one logical router,the authors generate a logical route-level topology with as small a cost as possible in terms of measurement overhead and use statistical data to estimate the traffic among *** comparing with partial true topology in geolocation,the logical router level topology is reasonable *** this paper the authors describe our method by measuring china Telecom’s router-level topology.

Based on the analysis of current Quality of Service (QoS) management on IP network, new genera-tion of QoS architecture QoSAF is proposed. QoSAF is divided into three layers: resource control layer, net-work service layer and business layer. QoS management is accomplished by interactivity of layers. In this ar-chitecture, mechanism of feedback control enhances the functions of resource management and system moni-toring. The principle of design and logical architecture of system is discussed in detail.
