Application In The Intellective Family And Studying Of Vital Technology Of IS-95

This task comes from subordinative project of the constructer administer-city public business governed system, This project is studying the methods of realization intelligent family. Through the combination with geography information system, information pad is set up in the family .Via it, controlling data and information data are exchanged about device using electricity between the family and the exterior . in family we can establish the network using blue-tooth and through the ISDN , wireless , cable , optical cable and so on outer family .It will have a good base for the digital city and digital earth.The paper is based on the overall demand of task and presented the new wireless transmit model of intellective family. That is IS-95CDMAModel. Firstly, all the controlling information and data is processed and enable them meet the demand of IS-95 standards. Then they are transmitted in reverse link channels of IS-95. The master of family and community can receive these information, Then they can control and manage equipment that uses the electricity of the family as well as exchange the information .On the side , the paper aims at the capacity of IS-95 system and bases on the character of the chaotic system , it studies a series of questions using chaotic sequence as Spread-frequency code .In order to build the versatile hardware pad , DSP and CPLD were used the paper gives out the concrete realization of the transmitting system about data and the method of realization of chaotic sequence in the versatile hardware pad.The test is operated on PC and in the help of CCS software thoughtthe special debugging software of series port. The experiment proves that this method is both right and practical.
