04 Sep 2006 20:17 cdma synchronisation vhdl

u say u didn't see channel model but if u can SEE the above posts u would find that it's a real channel & NO need for channel models here,
the synchronization u didn't SEE was in pilot detection techniques .... do u SEE people post much details then what i did
the question now is for u ..do u think couple of FPGA boards connected through direct meduim need somthing more of what u said u couldn't SEE ??!!!
by the way is that way of talking u use is NORMAL ??!!!

Do you know of a good forum like this to discuss implementation of comm algos/systems on c6713

i am trying to using your steps but i can`t get link
MATLAB> Open> Model file> Tools> HDL coder> Generate HDL.so tell me which version of matlab u had use.i am using matlab 7

hi ronak where r u? i am waiting for your replay.
i can`t find above link. i have simulink version of 6.6.may be this will in newer version of simulink.i think i need simulink hdl coder for this.if u have it than send me as soon as possible.or please send me exact path step by step.

first start making codes for digital cdma in matlab.make .m file for project.use function for that....function creates ur indivdual .m file.
and see simulation result figures...

now make .m file for sine of cosine wave as msg signal of cdma,u may use 8-bit quantization at tx side.and 8- bit dequantization at Rx side, by just editing ur old project of digital cdma.

now ,inspite of using sine or cosine wave make speech signal by passing while noise from 4.KHz lpf.

i had completed upto auto-correlation part of ds-cdma,but did give .m file to u.(i hope u make it and its neccesory to built ur own model for cdma.)

then after try to make enhanced .mdl file then me.hdl coder converts it into .v or .vhld file.

which fpga u r going to use?altera or xilinx?
if u r using altera EP2c8 series i have other new and easy option to make a project
in "C"....

hi ronak
thank u for your replay.
i am using altera.
i have comleted my .m file by my own logic but i had`t use fuction for that. i have run your cdma.mdl but can`t run dscdma.mdl can`t generate test bench for it.
so can u please send me some other document regarding your project. i have read your project report.

is the information will be transmitted through RF antenna ?
what is the band width of used antenna ?

can you suppose on me how can I implement CDMA and GSM standards on same FPGA?

thanks

i need help in simulation part.theory of cdma is cleared.i need imformetion about parameter of all blocks,function of all blocks and how waveform look like after each blocks.esspecially integration & dump block.i can`t understand it (in dscdma).do u implement as same block dia gram as this forum shown(on 1st page,1st block diagram)

hi deepak
about which project u asked? u already complete this project.so?
anyway send me your materials also.please send me all details of your project with block dia,figures,results etc.wich can be very useful to me in my project. thank u very much for your response.

soory,no.i dont have matlab write now.m on my job place.
do simulation by ur ownself...
but i may be help u...
1.see example project (.mdl file) of matlab7.1...
2.go to toolbox of simulink,there u will find one option to config. type of all model links...
3.set i/p,o/p,links between to models as u required.say suppose u int8,int16,unsiged int....
4.bcoz data type must be mached between all connection...
5.1st make simple .mdl file as in project,that is easily simulated in hdl coder...that genrates the vhdl code...
6. make project in quatus to download bit file into fpga....

Added after 2 minutes:

hodahussein,..
yes it can...
but it required addtion rf h/ws....

sorry 4 late reply.....
6. one is in IDE tool of altera named as quatus make a new project for ur altera device.....and pest the .vhd file into it...
simulate it on it....
u can make test bench file for project to in matlab,that is one or the advantage of using matlab simulator....
u jus put timing delay in test file to simulate real it chip respose.....in software named modelsim...
okay....
r u gujarati,indian???
whr r u frm????
m at baroda....

Added after 1 minutes:

hey...coolraj read my file yr project.....which i hv already uploaded on this page...
by understand it u will get idea....

i am from surat. and i am p g student. i am also studying in vv nager gcet(m.e communication). had your project run on fpga kit? can u give me your matlab code?please............

Added after 8 minutes:

have u generate vhdl code & test bench from your model? if u can & send me
