CDMA is not just a modulation scheme so you do not have simple transmitters or receivers for it you need complete CDMA module for the purpose. Qualcomm is the main CDMA chipset manufacturer. go to
http://www.qualcomm.com/
or get complete modules from

Xilinx have a CPLD mp3 player project demo on their website with all the HDL source code and schematics. That might be useful. Just go to xilinx website and search for mp3.
No there is no relation between the main board and the FPGA. But there can be a couple of problems. One your parallel port might have problems. Or the cable might not be good. Or you could have busted the parallel to JTAG interface on the FPGA board.
Re: help on fpga
The design warriors guide is a good starting point about FPGA. But it would not teach you any thing about actual implementation. You must get a book that teaches FPGA based design from ground up.
VHDL programming by example ( available here)
is such a book . Teaches you how...

That is true
Going directly to Patterson's book is not a good idea. It assumes that you have some basic computer architecture knowledge. We are talking about the " Computer Architecture a Quantitative Approach" here.
You can start with...
Re: help req for 16bit fpgacpu, organization and arch proble
Download McGraw.Hill.VHDL.Programming.by.Example.4th.Ed.pdf from here i.e EDA board. This book is all about designing a 16bit CPU in VHDL simulating it and implementing it on an altera FPGA. I used this base 16 bit CPU to implement my...
vhdl traffic light
you can download the Programmable Logic Design Quick Start Hand Book from the XILIX website. It has a complete example traffic light design. It is basically in the form of a tutorial.
You can use the GCK0, GCK1, GCK2, GCK3 pins . These go directly to the DLLs. You can make your signal behave as a clock and use the risingedge or fallingedge function. These pins are fixed and you have to rout your signal to one of them.
