用VB编写的源代码，抽注器（作为购买彩票时的一个依据）

viterbi 硬判决是指解调器根据其判决门限对接收到的信号波形直接进行判决后输出0或1，换句话说，就是解调器供给译码器作为译码用的每个码元只取0或1两个值，以序列之间的汉明距离作为度量进行译码，适用于二进制对称信道（BSC）

资源描述Abstract Considering rapid developments in the technologies of both radio-frequency identification (RFID) systems and wireless sensor networks (WSN), an integration of the two technologies may lead to the formation of an RFID-enhanced WSN which would possess improved functions and capabilities. In the RFID-enhanced WSN, many reader-enhanced nodes have increasingly been employed. In such networks, RFID data contains a lot of duplication, because the same tag may be read multiple times, and collision may occur among readers, while energy constraints are also a serious problem. These three could in turn cause serious problems. In this paper, we have proposed our CSMA-based algorithm since it is light, efficiently minimizes all kinds of reader collision, and eliminates the duplicate data. For this purpose, we have used a separate control channel and a tag ID forwarding mechanism with a special co

自适应的kalman滤波程序,通过灵活的调用，实现kalman的自适应滤波。-kalman_filter

LZW压缩，实现文本的压缩，压缩比在2:1以上 ZW算法基于转换串表（字典）T，将输入字符串映射成定长（通常为12位）的码字。在12位4096种可能的代码中，256个代表单字符，剩下3840给出现的字符串。

A Kalman filter is a stochastic , recursive estimator , which estimates the state of a system based on the knowledge of the system input, the measurement of the system output, and a model of the relation between input and output.
