    Performance analysis of zero-forcing coordinated MIMO transmission in interference channels by Hai-rong WANG, Jian DONG, Yong-ming HUANG, ANGLV-xi Y

    Published 2012-12-01
    “…The performance of the zero-forcing (ZF) coordinated transmit strategy in multiple-input multiple-output (MIMO) interference channels was investigated.With the goal to derive analytical expression of its performance metric such as the sum rate and the outage probability,the asymptotic behavior of the performance metric was examined with the MIMO dimension tending to infinity.Using the random ma ix theory,an asymptotic estimate of all the eigenvalues of the effective channel matrix in the ZF coordinated transmit strategy was first proposed.Based on that,two closed-form expressions of the sum rate were derived,from which the scaling law of the sum rate with the MIMO dimension was obtained.Furthermore,using the multivariate statistics about the probability density distribution of the minimum eigenvalue of a Wishart matrix,the analytical expression of the outage probability for the coordinated transmit scheme was achieved under two special cases.Simulation results show that the proposed tical expression of the performance metric is valid not only in the large-dimension regime,but also in the normal-dimension regime.…”

    Chain structure Bluetooth scatternet topology formation algorithm and performance simulations by YANG Fan, WANG Ke, QIAN Zhi-hong

    Published 2006-01-01
    “…A novel chain structure Bluetooth scatternet algorithm for topology formation was presented:all Bluetooth nodes turn into INQUIRY or INQUIRY SCAN states with identical probability,0.5,then set point-to-point connections up simultaneously.As a result,as large as possible numbers of temporary piconets were made up,and furthermore,some larger piconets and groups composed of several piconets were made up through varieties of merging and recomposing repeatedly.Finally,a chain structure scatternet bearing only one group were formed by operating the algorithm after several times.Simulations and performance analysis indicate that the scatternet formed by this algorithm has excellent characteristics:comparably less number of piconets,less average number of roles every node and less number of maximum degree of nodes,shorter networking establishment time,easier to maintain topology dynamically and dispensable for all nodes to be in communication range,etc.The algorithm can be used for Bluetooth scatternet topology formation.…”
