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几out— putting signal’S jamming peculiarity ale explained．At last，these time series models ofnoise FM jalllIIling sig— nal and几outputting signal ale built．

acm HDOJ 1051WoodenSticks Description: There is a pile of n wooden sticks. The length and weight of each stick are known in advance. The sticks are to be processed by a woodworking machine in one by one fashion. It needs some time, called setup time, for the machine to prepare processing a stick. The setup times are associated with cleaning operations and changing tools and shapes in the machine. The setup times of the woodworking machine are given as follows: (a) The setup time for the first wooden stick is 1 minute. (b) Right after processing a stick of length l and weight w , the machine will need no setup time for a stick of length l and weight w if l<=l and w<=w . Otherwise, it will need 1 minute for setup.

This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm is based on the interpolation technique for two correlation values in the frequency and phase domains. This simple interpolation technique can significantly improve frequency and phase resolution capabilities of the proposed technique without increasing the number of the correlation values. In addition, the overall block diagram of a digital communications receiver for DVB-RCS is presented, which was designed using the proposed estimation algorithms. Index Terms—Carrier phase estimation, DVB-RCS, frequency offset estimation, interpolation, joint estimation, MF-TDMA.

小程序应有如下功能： 1、登记。登记每位同学的上网卡号，押金(>=5 RMB)和上网时刻。 2、查询。可以查询每个上网卡号的上网时刻，上网的时间，押金和当前的费用。 3、结账。根据卡号可以算出 应收金额，应找金额。 4、提醒。当某个上网卡号的 上网费用 >= 它的押金时应提醒管理员。 5、续费。当某个上网卡号的 上网费用 >= 它的押金，他可以再次交上一定金额的押金(>=5 RMB)。 6、修改费率。上网的费率应可以调整。默认的费率是1 RMB /1小时。 为了不让机房赔本，应是这样的收费模式：先付钱后上网。如上机就五角， 以后过半小时收五角。 7、总账。一天下来管理员要知道这天他赚了多少RMB。 你需要考虑程序被意外结束等特殊情况。 如果你的程序是按系统时间进行计时，还应考虑系统时间被意外更改的特殊情况。总之，你应考虑一切会让你的程序不能正常运行的特殊情况。 如果不知道怎么计时，你可以学习参考使用<time.h>中函数。 说明： a. 假定机房有150台机器。 b. 假定初始的费率是1 RMB /1分钟(便于测试)。

The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity． The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions．However．there are many shortcomings in traditiona1 measurements．This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page．Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e币cient．

Circular Convolution of two equal-length vectors. Highlights that circular convolution in the time domain is the effectively the same as element-by-element multiplication in the frequency domain.

This small utility helps to generate seven segment display codes for different I/O connections. For example, AVR/PIC Port A.0 -> D Segment Port A.1 -> B Segment .... Also it can generate Common Cathode or Common Anode table codes.. I Coded it long time ago. I Hope help someone. Thank you
