The precondition of the whole known channel state information (CSI) is impractical in realistic system. To deal with this problem, a partial CSI based Affinity propagation Dynamic clustering algorithm was proposed in thispaper. In this algorithm, degree of wiliness to cooperate (DWC) was used to design the input matrix and a cooperation fact was introduced to adjust the number of clusters in clustering...
In this paper, a cumulant-based DOA estimation algorithm, is presented for DS-CDMA system under multi-user environment. Simulations results show that the algorithm is much better in DOA estimation precision and resoling capability than the conventional MUSIC algorithm.
Quality-of-service routing (QoSR) is a challenging NP-hard problem of IPv6 networks. For the sake of satisfying QoS requests of future multimedia applications, a novel LMA (link-utilization-ratio metric based routing Algorithm) is proposed. It takes only a single metric called LUR (link-utilization-ratio) as the link cost, which is advertised suitably by OSPFv3 LSAs of IPv6. It computes routing by...
