This my phd thesis for the WDM optical network optimization, which employs convex optimization techniques to solve the proposed integer problems. The computation complexity of my optimization framework is very low compared with other existing method and a performance bound is provided at the same time.

We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation, phase-shift keying, and pulse amplitude modulation communications systems.We study the performance of a standard CFO estimate, which consists of first raising the received signal to the Mth power, where M is an integer depending on the type and size of the symbol constellation, and then applying the nonlinear least squares (NLLS) estimation approach. At low signal-to noise ratio (SNR), the NLLS method fails to provide an accurate CFO estimate because of the presence of outliers. In this letter, we derive an approximate closed-form expression for the outlier probability. This enables us to predict the mean-square error (MSE) on CFO estimation for all SNR values. For a given SNR, the new results also give insight into the minimum number of samples required in the CFO estimation procedure, in order to ensure that the MSE on estimation is not significantly affected by the outliers.

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.

這兩個函數 function app_path1:string function socket_rec_line1(socket1:TCustomWinSocket timeout1:integer crlf1:string=#13#10):string 實際上是我的一個公用單元中的函數，大家應該養成建立自己的公用單元的習慣。 socket_rec_line1函數中用了唐曉峰大俠的coolmail中的辦法：只是簡單的一個一個字節收取，找到結束 標志后就算收完一行了，大家實際應用時可能應該找更好的辦法。 這個程序的目的是：flashget在下載象51.net系列[如我的clq.51.net]中的程序時，會因為這些網站上的 自定義錯誤頁面而導致下載的文件出錯，具體見“大富翁”上的 “http://www.delphibbs.com/delphibbs/dispq.asp?lid=1170159” 雖然這是一個演示程序，不能下載地址轉向的東東。但對于固定地址文件的下載已經很不錯了，我的公司 不能裝多線程的東東我一直用這個下載我要的大文件，“大富翁”200多M的離線數據這是用它下載的。

轉載一個程序。 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.

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.
