This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise.
The packet include:
1) Packet Builder (Viterbi Encoding, Interleaver, PN generation)
2) Modulator (RRC filter)
3) Demodulator (Matched Filter, RAKE receiver)
4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).
You should run "Simulation.m" function that include all modules.
DES( Data Encryption Standard)算法,于1977年得到美國政府的正式許可,是一種用56位密鑰來加密64位數(shù)據(jù)的方法。DES算法以被應(yīng)用于許多需要安全加密的場合。(如:UNIX的密碼算法就是以DES算法為基礎(chǔ)的)。下面是關(guān)于如何實現(xiàn)DES算法的語言性描述,如果您要其源代碼,可以到Http//Assassin.yeah.net下載,后者您有任何問題也可以寫信給我(Assassin@ynmail.com)。
本文將介紹如何使用Sun公司的最新《Java Data Objects 》規(guī)范來進(jìn)行基于數(shù)據(jù)庫的簡單應(yīng)用程序的開發(fā),從而使讀者對JDO有一個直接的感性的認(rèn)識,為更深入的開發(fā)作鋪墊,同時也希望拋磚引玉,讓更多的富有經(jīng)驗的高手也參與到推廣JDO的進(jìn)程中來,為讀者提供更多更精彩的文章!
* A ncurses user interface.
* Network statistics to view the amount of packets and data in many
different protocols, interfaces and hosts.
* View what active TCP connections are on the network.
* View UDP packets.
* View and log ICMP packets.
* View and log the 48bit arp protocol.
And also view what make of network card is in each machine
* Multithreaded so that the user interface does not interfere with any of the packet
captureing methods.
* View and log the following user space protocols
FTP, POP3, HTTP
