DS-CDMA chip on xilinx FPGA...hlp me...

matlab program multichannel ds-cdma system

hi.guys.i m going my final year project on imple. cdma chip on FPGA.
m goal are...
1.generating .m file in matab for multi-channel users(only binary data sequnce).
2.now generating .m file for analog speech signal,too...
3.now,change hadamard code sequnce in proper time delay,for better sequrity of ds-cdma.
4.add noise before my datas are transmitted...
5.at last covert .m file in .hdl file using simulink coder 1.4 of matlab.
6.load it into spartan kit,syncronize kit by proper time functions.
7.get result on output for multiple users(for binary data-m using rs-232 to get,see output).

i did goals 1.,3.,4. very nicely...
but i got problems in remainings...
my ques r....
1.how i go for analog speech signal of voice on fpga.
bcz till now i study verilod hdl for only digital datas.
2.how to make filter in .m of matlab.
3.than how to convert .m into .hdl().this is my big problem.
4.which software may i use for converting .m to .hdl?????[/b]

fpga cdma

I am not very qualified to answer this but from my experience only SIMULINK blocks can be converted to HDL such as verilog or Vhdl. Also these simulink blocks should be from vendors like Xilinx (System generator) or Synplify (SynplifyDSP) or Altera (System builder).

core files for ds chip

you can convert from matlab source to vhdl under certain conditions
that type of programs are called synthetizers. There is Accelchip that does that type of matlab to vhdl synthesis .But is pretty expensive !
if you use matlab internal functions you better be shure that the software that converts to vhd supportes them (you should say synthetize them).
You can also use simulink toolboxes and convert your matlab code to simulink and use xilinx blocksets and use system generator to produce a fpga core .
This is the cheapest way to do it .And is very easy to do simulation and co-verification .

Otherwise look for AccelChip or xilinx's acceldsp and accelware which is a collection of matlab synthetized libraries and be prepared to pay big money ! www.xilinx.com/support/sw_manuals/acceldsp_style.pdf

ds cdma + fpga

the best solution is to use systemgenerator
if you need any help regarding that, please go ahead and ask me, i've worked a lot with that tool and prepared tutorials for it as well

mr.ronak shah
NOW as you have completed your project
i have looked at your work its phenomenal i have a project of implementation of cdma on FPGA platform for completion of my BE degree i need some more help regarding choosing of FPGA ki do i need RF module on it also?
