CDMA LSI Chip Set




CDMA Portable/Mobile Phone Systems

First, consider the signal flow during
reception. Figure 1 shows a block
diagram of a CDMA portable phone.
The very weak receive signal from a
base station is down-converted to the IF
frequency band by the RF receiver, and
amplified by the RX AGC unit. The IF
signal is down-converted to an analog
baseband signal by the analog baseband
processor, and then the analog signal is
c ....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

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

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

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

In the development of packaging of electronics the aim is to lower cost, increase the packaging density, and improve the performance while still maintaining or even improving the reliability of the circuits. Flip chip microelectronic assembly is the direct electrical connection of face-down electronic components onto substrates, circuit boards, or carriers, by means of conductive bumps on the chip bond pads since the chip is directly attached to the substrate, board, or carrier by the conductive bumps. Flip chip has advantage in size, performan ....etc

Electronics without silicon is unbelievable, but it will come true with the evolution of Diamond or Carbon chip. Now a day we are using silicon for the manufacturing of Electronic Chip's. It has many disadvantages when it is used in power electronic applications, such as bulk in size, slow operating speed etc. Carbon, Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors in normal temperature. So in the earlier days they a ....etc
