Analysis and Design of Interleave-Division Multiple-Access in
Labview Software.



Introduction to Labview:
LabVIEW (short for Laboratory Virtual Instrumentation Engineering
Workbench) is a platform and development environment for a visual
programming language from National Instruments. The purpose of
such programming is automating the usage of processing and
measuring equipment in any laboratory setup.
The graphical language is named G (not to be confused with G
code). Or ....etc

Time Division Multiple Access (TDMA)

TDMA, or Time Division Multiple Access was one of the first cell phone digital standards available in the United States. It was the first successor to the original AMPS analog service that was popular throughout the country, and was in popular service from the early-mid 1990's up until roughly 2003 when the last of the TDMA carriers, Cingular and AT&T, switched to the GSM digital standard.

TDMA was a significant leap over the analog wireless service that was in place at the time, ....etc

INTRODUCTION
WCDMA stands for Wide Band Code Division Multiple Access.
W-CDMA is a Third-Generation(3G) mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices than commonly offered in today's market.
It is specified by 3rd Generation Partnership Project (3GPP).
It is the key technology for UMTS.
HISTORY
QUALCOMM , the first company to succeed in developing a practical and cost effective CDMA implementation for co ....etc

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
converted to a digital signal. This digita ....etc

Abstract:
Orthogonal Frequency-Division Multiple Access (OFDMA) is a multi-user version. Multiple access is achieved in OFDMA by assigning subsets of subcarriers to individual users. This allows simultaneous low data rate transmission from several users, OFDM is sometimes referred to as discrete multi-tone modulation, instead of a single carrier being modulated, a large number of evenly spaced subcarriers are modulated using some m-ary of QAM. This is a spread-spectrum technique that increases the efficiency of data communications by increasin ....etc

Orthogonal Frequency Division Multiple Access (OFDMA) is a multiple access scheme for OFDM systems. It works by assigning a subset of subcarriers to individual users.



OFDMA features

*

OFDMA is the 'multi-user' version of OFDM
*

Functions by partitioning the resources in the time-frequency space, by assigning units along the OFDM signal index and OFDM sub-carrier index
*

Each OFDMA user transmits symbols using sub-carriers that remain orthogonal to those of other users
*

More than one sub-carrier can be ....etc
