Direct sequence spread spectrum digital Radio DSP prototyping using xilinx FPGAs
Spread spectrum digital radio receivers and transmitters are very difficult to simulate for overall system performance evaluation. Reliable estimates for Bit Error Rates and effect of indoor and outdoor fading radio channels can be best studied via practical hardware measurements. In this work we propose a flexible CDMA spread spectrum radio architecture structure well suited for FPGA prototyping. FPGA based rapid system prototyping techniques provide complementary information than simulations and also facilities earlier system integration activities across different project groups.
