本文探討了其中的兩個問題: 1 .在跟蹤蜂窩移動通信網路中移動終端的運動軌跡時,如何利用粒子濾波器減弱非直達波傳播對濾波跟蹤演算法精度的顯著影響In wcdma system which uses direct sequence to spread spectrum, the spread spectrum code ( pn code ) phase of the receiver must be synchronized with that of the received signal precisely to despread and demodulate the signal correctly. multipath channel exists in the mobile communication environment for the radio signal reflection by obstacles between transmitters and receivers. by using the autocorrelation of the spread sprectrum code, rake receiver can process received signals and therefore multipath components can be resolvable
在wcdma系統中,為正確解擴解調接收到的擴頻信號,接收機本地產生的擴頻碼( pn碼)相位必須和接收信號中的擴頻碼相位完全同步;同時移動通信環境中的傳輸信號由於接收機和發射機之間的直達路徑有可能被建築物或其他障礙物所阻礙,總是經過折射或反射的多條路徑后才到達接收機,從而產生多徑通道。Travelling wave tubes ( twt ) are the heart parts of radar systems , communication systems , electronic countermeasures , remote - control & test device , accurate guidance equipment, etc. as the main component of the beam - wave interaction of a travelling wave tube for producing microwave energy, the solw - wave structure ( sws ) is the key of the twt. it basically determines the performance of the twt
行波管是雷達、通信、對抗和精密制導等設備的「心臟」 ,而慢波系統作為行波管進行注波互作用激勵微波能量的主要部件,是行波管的核心,其性能優劣直接決定高功率微波源的性能。Transmition velocity relys on the style of encode and modulation essentially during modern data transmition for the quality of using line bandwidth and the immunity of code ties on them tightly. but it is important that the velocity of data transmition reaches its limitation in fact for the interface of environment and cross - talk. so for the improvement of transmition velocity, we must analyze the characteristics of noise signal and the model of line deeply and then take some useful measures to better the immunity of modulation wave
在現代通信的數據傳輸過程中,傳輸速率本質上是由傳輸的編碼方式和調制方式決定的,因為編碼方式和調制方式直接決定了線路頻帶利用率和碼元抗干擾能力的好壞,因而直接決定了傳輸速率;但是在實際應用過程中,數據傳輸速率是不可能達到理想狀況的,因為環境干擾、串音干擾等因素的存在使得線路的頻帶不可能被完全利用起來;因此,必須認真分析線路的噪聲信號的特性以及噪聲線路的模型,以便在編碼方式和調制方式中針對性的做一些改進措施以改善調制波形的抗干擾能力,使得傳輸速率能夠進一步提高。Socket function mainly realizes setting up and initializing service unit socket, initializing service unit and service unit serial and so on. bind funcion primarily binds local address and port for the socket. listen function is to evaluate the max length of server ’ s listening queue. connect function and accept function set aside rate ahead, infrom user ’ s request of establishing virtual circuit to suna, cooperate with suna to establish the connection between client and server, return the result. we make use of three handshake with data protocol and virtual circuit mode, in this way, when we translate data, we can look up communication course according to virtual circuit number, at the same time, there aren ’ t source ip address and port, end ip address and port in the head of data package, the speed of translating data advances in a certain extent. send function and recv function is to send data collaborating with suna, and copy data from the receiving queue of socket to user ’ s buffer. close function cooperate
Socket ( )函數實現創建、初始化服務元套接字,初始化服務元及服務元序列等。 bind ( )函數為套接字綁定本地地址和埠號。 connect ( )和accept ( )函數主要是根據用戶要求預留帶寬,將用戶的建立虛電路請求轉達給服務元網路體系,協作服務元網路體系採用捎帶數據的三次握手協議建立虛電路,並告訴用戶處理結果,一方面,捎帶數據的三次握手協議在一定程度上可提高數據傳輸速度;另一方面,採用虛電路方式,使得數據通信可直接根據虛電路號查找相應的通信進程,而且數據包的包頭中省去了源ip地址、埠號和目的ip地址、埠號,提高了數據傳輸速率。The second channel is a transponder with no guard. it can be used in the relay communication system and can be composed into a data platform with remote control if additional terminal equipment is added. its application in other systems is also discussed
