Abstract:Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it.Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorrelation method in this paper.It’S jamm g peculiarity and幾out— putting signal’S jamming peculiarity ale explained.At last,these time series models ofnoise FM jalllIIling sig— nal and幾outputting signal ale built.

Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

design LP,HP,B S digital Butterworth and Chebyshev filter. All array has been specified internally,so user only need to input f1,f2,f3,f4,fs(in hz), alpha1,alpha2(in db) and iband (to specify the type of to design). This program output hk(z)=bk(z)/ak(z),k=1,2,..., ksection and the freq.

About: hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases. Release focus: Major feature enhancements Changes: This release comes with many changes and new features. It can manage multiple databases in one file. A new flag (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download. Author: cruppstahl

Floyd-Warshall算法描述 1)適用范圍: a)APSP(All Pairs Shortest Paths) b)稠密圖效果最佳 c)邊權可正可負 2)算法描述: a)初始化:dis[u,v]=w[u,v] b)For k:=1 to n For i:=1 to n For j:=1 to n If dis[i,j]>dis[i,k]+dis[k,j] Then Dis[I,j]:=dis[I,k]+dis[k,j] c)算法結束:dis即為所有點對的最短路徑矩陣 3)算法小結:此算法簡單有效,由于三重循環結構緊湊,對于稠密圖,效率要高于執行|V|次Dijkstra算法。時間復雜度O(n^3)。 考慮下列變形:如(I,j)∈E則dis[I,j]初始為1,else初始為0,這樣的Floyd算法最后的最短路徑矩陣即成為一個判斷I,j是否有通路的矩陣。更簡單的,我們可以把dis設成boolean類型,則每次可以用“dis[I,j]:=dis[I,j]or(dis[I,k]and dis[k,j])”來代替算法描述中的藍色部分,可以更直觀地得到I,j的連通情況。
