cdma project

hi every1 i've just finished CDMA project on FPGA boards the design is from A-to-Z DIGITAL even the summation process if any1 interested i can give a hand...,
 

cdma circuits+fpga

We are glad to know the completion of your project on CDMA. I have just submitted the proposal on the same topic so could you please give us the advice for proceeding the project and some details of yours.
thanks ..
 

cdma handset block diagram

could you please give us the advice for proceeding the project

first of all u have to learn about CDMA if u don't have a background yet u can start with the following book "technical introduction to CDMA" u can find it on


the other main part is FPGA board & how to program it ... i recommend VHDL to do so;

after u r familier with these two parts u can go ahead in the design

& i would be glad to answer any questions regarding the project -isa-
 

example design for implimenting cdma in fpga

han00oo, I saw the block diagram of your system. Could you please send the diagram interms of logic gates?
You said "even summation in DIGITAL", did you use XOR gate or OR gate for that purpose?

regards
M

ok..here what i did : i converted digital signal to physical signal & then summation process held & again i returned the summation to Binary before transmission...
did any1 use this technique ???
 

hi for any1 wanna learn about CDMA here's agood PDF book to start it's the most interesting book i've ever found regarding CDMA you can download from this link
"How CDMA works":

Basic CDMA Principles
• Coding
• Forward and Reverse Channels
CDMA Operational Details
• Multiplexing, Forward and Reverse Power Control
CDMA Handset Architecture
CDMA Handoffs
CDMA Network Architecture
CDMA Messaging and Call Flow
Optional Topics
Wireless Multiple Access Technologies
Overview of Current Technologies
• Capacity; CDMA Overlays, Spectrum Clearing
 
spectrum analyzer project fpga

here am gonna start posting more details about my project for any1 interested in CDMA

Part 1 : introduction to :Spread spectrum,FPGA spartan-3 & VHDL


& i'll continue next parts in next posts -isa-
 

make ur fpga

HanOOoo, could you please give the detail of how the link was made between the transmitter and the receiver?

Regards,
rectifier.
 

cdma sur fpga

could you please give the detail of how the link was made between the transmitter and the receiver?

well , first we wanted the channel to be wireless but we run out of time so we replaced it with wired channel
 

project report on cdma

hanOOoo, did you check the spread spectrum using spectrum analyser?? If you did could you post the pics or any data regarding that.

Regards
M
 

fpga & cdma technique

each block in the uploaded files followed by simulation for it, but this is from Modelsim in FPGApro tool not using spectrum analyser
 

current cdma project

Could you please post the remaining part of your project?

thanks ,
rectifier
 

project report on fpga

hanOOoo, did you face any "synchronization" problems during your project. For instance, alignment of data bit with PN code width?
