This is the second in a two-part series of papers on statistical performance analysis of a general cross-layer automatic repeat request（ARQ）cooperative diversity（ACD）*** order to obtain the theoretical formulas of end-to-end performance parameters,we develop a time division multiple access（TDMA）-based absorbing Markov model to help find all possible transition probabilities of each transmission *** on this model and statistical analysis,we derive two tight closed-form expressions in terms of packet delivery failure probability and packet delivery delay *** addition,simulation results by Monte Carlo simulations demonstrate the correctness of our analysis eventually.

第24届中国控制与决策会议

作者： Hong Yang 1 , Le Zhang 1,2 1. school of information engineering, Shenyang University, Shenyang 110044, china2. school of electronic and information engineering, Dalian University of Technology, Dalian 116023, china

Average dwell time technique is an effective tool to study switched systems, but which has not been yet applied to study switched fuzzy delay systems. This paper deals with the problem of exponential stability for switched fuzzy systems based on this method. First, a model of a kind of uncertain switched fuzzy systems is presented, in which each subsystem is an uncertain fuzzy system. Then, based on Lyapunov functional candidate and average dwell time scheme, linear matrix inequalities’ （LMIs’） conditions are presented to guarantee robust exponential stability of the switched fuzzy delay systems. The exponential decay estimate for state is also explicitly developed. At last, two numerical examples are given to illustrate the effectiveness of the proposed method.

＜正＞ A new algorithm for supervised pattern identification based on Particle Swarm Optimization （PSO） is proposed in this paper. At first, an image database with training image samples is set up. Secondly, image samples to be identified and stored in the database are preprocessed. Then, point matching is made between the identified images after preprocesing with the training images after preprocesing by using PSO, respectively. Finally, the identification is realized by seeking the minimum of a defined classification function. This algorithm is approved to be effective, accurate and simple by the experiments.
