Applying CDMA Technique to Network-on-Chip
The details of applying a code-division multiple access (CDMA) technique to an on-chip packet switched communication network is described in this article. Here, VHDL is used to implement a packet switched network-on-chip (NoC) that applies the CDMA technique at the RTL level. The globally-asynchronous locally-synchronous (GALS) communication scheme is supported by the chip so developed. a point-to-point connection schemes data transfer latency is reduced by this NoC by sharing the data commu ....etc

The world is demanding more from wireless communication technologies than ever before. More people around the world are subscribing to wireless services and consumers are using their phones more frequently. Exciting Third-Generation (3G) wireless data services and applications - such as wireless email, web,digital picture taking/sending and assisted-GPS position location applications - and wireless networks have also arrived and asked to do much more than just a few years ago. This is where CDMA technology fits in. CDMA consistently provides be ....etc

Overview
Code division multiple access (CDMA) is a modulation and multiple-access scheme based on spread-spectrum communication. In this scheme, multiple users share the same frequency band at the same time, by spreading the spectrum of their transmitted signals, so that each user's signal is pseudo-orthogonal to the signals of the other users.

CDMA Signals
In a CDMA system, each signal consists of a different pseudorandom binary sequence (called the spreading code) that modulates a carrier, spreading the spectrum of the waveform. A large ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc

The Internet and Mobile Wireless are the defining technologies of our times. Today, they are converging and promising to dramatically reshape society. Mobile Internet services will help people work, entertain, and communicate anytime, anywhere-using a variety of devices such as cell phones, Personal Digital Assistants (PDAs), and laptops. Driven by the Wireless Internet?s enormous potential and reacting to declining Mobile voice revenues per subscriber, operators are pegging their future growth on Wireless Internet services.

While operators ....etc

Multiple access (MA) schemes are used to simultaneously share available bandwidth in communication systems. In conventional MA applications a finite and contiguous amount of spectrum which is designated for a particular service is allocated to multiple users. Therefore, the use of designated radio spectrum is unconstrained and can be utilized in many ways to achieve maximum efficiency. Time division multiple access (TDMA), frequency division multiple access (FDMA), and code division multiple access (CDMA) are the three major MA techniques. In r ....etc
