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 recent years large scientific interest has been devoted to joint data decoding and parameter estimation techniques. In this paper, iterative turbo decoding joint to channel frequency and phase estimation is proposed. The phase and frequency estimator is embedded into the structure of the turbo decoder itself, taking into consideration both turbo interleaving and puncturing. Results show that the proposed technique outperforms conventional approaches both in terms of detection capabilities and implementation complexity.

An unsatisfactory property of particle filters is that they may become inefficient when the observation noise is low. In this paper we consider a simple-to-implement particle filter, called ‘LIS-based particle filter’, whose aim is to overcome the above mentioned weakness. LIS-based particle filters sample the particles in a two-stage process that uses information of the most recent observation, too. Experiments with the standard bearings-only tracking problem indicate that the proposed new particle filter method is indeed a viable alternative to other methods.

转载一个程序。 This zip file contains a example of using C++ language COM in a Visual C++ program (named example.zip), and a COM component built by comtool of Matlab and used in a Visual C++ program(named mycom.zip). Both projects contain fire_event in COM. But it only works well in the former example. The interface of two COM components looks very similar, and the client program of two projects are almost the same.

TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An extended search mode is available, where only letters and digits are relevant. Other options: case sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix

FIST可堆叠文件系统,linux文件系统修改相关的开源软件,使得对linux文件系统功能的改进很简单了 The FiST (File System Translator) system combines two methods to solve the above problems in a novel way: a set of stackable file system templates for each operating system, and a high-level language that can describe stackable file systems in a cross-platform portable fashion. Using FiST, stackable file systems need only be described once. FiST s code generation tool, fistgen, compiles a single file system description into loadable kernel modules for several operating systems (currently Solaris, Linux, and FreeBSD). The project demonstrates that with FiST, code size and development time are reduced significantly, while imposing a small performance overhead of only 1-2%. These benefits are achieved, as well as portability, without changing existing operating systems or file system.
