Do you have PowerPoint slides to share? Figure shows the idea behind TDMA. This video will show working of CDMA technology with the help of animation. In CDMA every user receive a unique code known as chipping sequence. The receiver picks out each channel from the noise using the code. Each station transmits its data in its assigned time slot.

Multiplexing and Multiple Access

Multiple Access An access network is that part of a communications network which connects subscribers to their immediate service provider. Multiplexing is sharing of resources on links inside the network i. The links between the network elements NEs of service provider or between two service providers Multiple Access is sharing of resources on the access part of the network. Two way communication 1. Inbound or forward link The communication link from the subscriber to the service provider via satellite. Outbound or reverse link The communication link from the service provider to the subscriber via satellite.

Frequency It is well-established technology and applied to digital cellular radio and wireless communication systems in the early s. Code Optimization Sept. Jamalipour et al. Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free. Multiple simultaneous transmissions are separated by unique code sequence. Or use it to upload your own PowerPoint slides so you can share them with your teachers, class, students, bosses, employees, customers, potential investors or the world. Many of them are also animated.

Abstract—To satisfy ever-increasing demands for higher data rates, as well as to allow more users to simultaneously access the network, interest has peaked in what has come to be known as wideband code division multiple access WCDMA. Whether your application is business, how-to, education, medicine, school, church, sales, marketing, online training or just for fun, PowerShow. CiteSeerX - Document Details Isaac Councill, Lee Giles, Pradeep Teregowda : Abstract—To satisfy ever-increasing demands for higher data rates, as well as to allow more users to simultaneously access the network, interest has peaked in what has come to be known as wideband code division multiple access WCDMA.

Using different orthogonal codes, interference between the signals is minimal. Also recognized as Wideband Code Division Multiple Access, WCDMA is one of the principles used for air edge which is presented by mobile telecommunications networks that give 3G services to their customers and patrons. Code division multiple-access CDMA Space division multiple access SDMA Depending on how the available bandwidth is allocated to the users, these techniques can be classified as narrowband and wideband systems. Many of them are also animated. In wireless communication systems, it is often desirable to allow the subscriber to send information simultaneously from the mobile station to the base station while receiving information from the base station to the mobile station.

A DSP-based cross-channel interference cancellation CCIC technique with initial condition-free, fast convergence and signal modulation format independence, is experimentally demonstrated in a two-channel point-to-point digital filter multiple access DFMA PON system based on intensity-modulation and direct-detection IMDD. The CCIC-induced transmission performance improvements under various system conditions are fully investigated for the first time.

Code-division multiple access

1. Introduction

In this bandwidth is divided into various frequency bands. Each station is allocated with band to send data and that band is reserved for particular station for all the time which is as follows :. The frequency bands of different stations are separated by small band of unused frequency and that unused frequency bands are called as guard bands that prevents the interference of stations. It is like access method in data link layer in which data link layer at each station tells its physical layer to make a band pass signal from the data passed to it. The signal is created in the allocated band and there is no physical multiplexer at the physical layer.

Беккер спустился вниз, постоял, глядя на самолет, потом опустил глаза на пачку денег в руке. Постояв еще некоторое время в нерешительности, он сунул конверт во внутренний карман пиджака и зашагал по летному полю. Странное начало. Он постарался выкинуть этот эпизод из головы. Если повезет, он успеет вернуться и все же съездить с Сьюзан в их любимый Стоун-Мэнор. Туда и обратно, - повторил он.  - Туда и обратно.

Камера последовала за Халохотом, двинувшимся в направлении жертвы. Внезапно откуда-то появился пожилой человек, подбежал к Танкадо и опустился возле него на колени.

Фонтейн повернулся к окну. - Господи Исусе. Раздался телефонный звонок. Директор резко обернулся. - Должно быть, это Стратмор.

Все как один были панки. И, наверное, у половины из них - красно-бело-синие волосы. - Sientate! - услышал он крик водителя.  - Сядьте.

Окно местоположения Следопыта откликнулось именно так, как он рассчитывал. ОТОЗВАТЬ СЛЕДОПЫТА. Он быстро нажал Да.

Сьюзан закрыла глаза, но ее снова вывел из забытья голос Дэвида. Беги, Сьюзан. Открой дверцу. Спасайся. Она открыла глаза, словно надеясь увидеть его лицо, его лучистые зеленые глаза и задорную улыбку, и вновь перед ней всплыли буквы от А до Z.
