A NOVEL SDR TRANS-RECEIVER ARCHITECTURE FOR COMMUNICATION SYSTEMS ON FPGA

Sharanling Majge, Prashant Bachanna

Abstract: Usage of Software-Defined Radio (SDR) in digital communication systems can easily cater to sophisticated coding and modulation techniques, to meet the ever-increasing requirements of the wireless communication industry. Future generation of wireless communications will meet the requirements of Software Radio technology as it would provide the state-of-art design to complex radio designs. Software-defined radios are configurable devices in which the components can be reprogrammed to emulate various functionalities like data rate, modulation, filtering etc. Field programmable architectures provide a suitable platform to achieve such run-time reconfigurations of the components of the radio. The proposed design is implemented in SPARTAN3 FPGA by using Xilinx ISE 13.4 and verilog and simulated in modelsim 6.3f. The Chipscope pro Analyzer is used to view the execution results of FPGA.
