The incremental finite mixture model is proposed for the multiple target state estimation in sequential Monte Carlo implementation of probability hypothesis density filter. The model is constructed in incremental way. It consists of two steps, the step of inserting new component into model and the step of estimating mixing parameters. The maximum likelihood criterion is adopted for both steps. At...
Conventional distributed Alamouti-like space-time block codes (STBC) transmission strategy in two-user cluster-based cooperative communication systems (Sushanta and Monisha, 2008) is extended to single-carrier frequency-domain equalization (SC-FDE) systems, and a two-user cooperative transmission scheme in distributed frequency division multiple access (DFDMA) systems is proposed for uplink wireless...
In this paper we propose a new resampling strategy about particle filter algorithm for tracking object in video sequence. We incorporate the new resampling strategy and adaptive elliptical template with the classical particle filter algorithm. We apply enhanced algorithm to track selected object in a standard video and demonstrate its performance compared with the algorithm proposed by K. Nummiaro...
A new two-user cooperative transmission scheme with low-complexity frequency-domain equalization (FDE) for single carrier frequency division multiple access (SC-FDMA) systems in localized subcarrier mapping mode is proposed for uplink wireless transmission in this paper. At the destination, each user's information can be obtained with a simpler diversity combing and a lower-complexity FDE than existing...
In this paper, the outage probability of space-time coded decouple-and-forward (DCF) relay network in Nakagami-m fading channels is analyzed. We derive both accurate expressions and closed-form bounds of outage probability by investigating the statistic property of sum of Gamma random variables. All the analytical results are confirmed through Monte Carlo simulations.
Cooperative diversity enables single antenna transmitter in a multi-user or relay environment to share the antennas so as to achieve diversity gain. In this work, the cooperative communication system with distributed Alamouti code is investigated, where amplify-and-forward (AF), adaptive decode-and-forward (DF) or hybrid AF/DF are used at the relay, with both Rayleigh fading and path loss effect introduced...
In this paper, we propose a latent factor regression model, in which priors are assigned to both the latent regression vector and the error term, by using reproducing kernels. The resulting regression function follows a stochastic process known as a student process. The model is attractive because its implementation is based on a tractable posterior predictive distribution and a simple expectation-maximization...
