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

[ronak shah]

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?????

4- to convert an m. file to VHDL you may rewrite it in an embedded matlab simulink block , then convert it using matlab ( 7.5 and higher).

Note : the coding technique must be changed to work in simulink environment ; the data is clocked at input.

when you reach this stage , if you need more details , tell me.
