This paper examines the asymptotic (large sample) performance of a family of non-data aided feedforward (NDA FF) nonlinear least-squares (NLS) type carrier frequency estimators for burst-mode phase shift keying (PSK) modulations transmitted through AWGN and flat Ricean-fading channels. The asymptotic performance of these estimators is established in closed-form expression and compared with the modified Cram`er-RAO bound (MCRB). A best linear unbiased estimator (BLUE), which exhibits the lowest asymptotic variance within the family of NDA FF NLS-type estimators, is also proposed.

In this article, we present an overview of methods for sequential simulation from posterior distributions. These methods are of particular interest in Bayesian filtering for discrete time dynamic models that are typically nonlinear and non-Gaussian. A general importance sampling framework is developed that unifies many of the methods which have been proposed over the last few decades in several different scientific disciplines. Novel extensions to the existing methods are also proposed.We showin particular how to incorporate local linearisation methods similar to those which have previously been employed in the deterministic filtering literature these lead to very effective importance distributions. Furthermore we describe a method which uses RAO-Blackwellisation in order to take advantage of the analytic structure present in some important classes of state-space models. In a final section we develop algorithms for prediction, smoothing and evaluation of the likelihood in dynamic models.

We present a particle filter construction for a system that exhibits time-scale separation. The separation of time-scales allows two simplifications that we exploit: i) The use of the averaging principle for the dimensional reduction of the system needed to solve for each particle and ii) the factorization of the transition probability which allows the RAO-Blackwellization of the filtering step. Both simplifications can be implemented using the coarse projective integration framework. The resulting particle filter is faster and has smaller variance than the particle filter based on the original system. The convergence of the new particle filter to the analytical filter for the original system is proved and some numerical results are provided.

跳變馬爾可夫模型狀態(tài)估計的粒子濾波算法研究，本文在系統(tǒng)分析傳統(tǒng)粒子濾波理論與應用問題的基礎上，重點研究了基于跳變馬爾可夫狀態(tài)空間模型的粒子濾波算法。針對混合系統(tǒng)在二維離散狀態(tài)情形下的混合狀態(tài)估計問題，給出了基于RAO-Blackwellised粒子濾波的二維離散狀態(tài)與連續(xù)狀態(tài)的同步估計算法，一定程度上緩解了傳統(tǒng)粒子濾波算法在高維狀態(tài)空間估計中的失效問題，有效提高了狀態(tài)估計的精度。應用數(shù)值仿真計算，對相關粒子濾波算法的性能進行了比較分析。結果表明，本文研究的算法能夠有效完成二維離散狀態(tài)與連續(xù)狀態(tài)的同步估計，其中，二維離散狀態(tài)的估計準確率達到了 96％。
