Baseband OFDM physical layer implementation on FPGA using SystemVue

OFDM (Orthogonal Frequency Division Multiplexing) technique is a multicarrier modulation technique in which data bits are transmitted in parallel over multiple subcarriers. Its main advantage to other techniques lies in its robustness against multipath fading and ISI (Inter Symbol Interference). It has widely gained acceptance and is the integral part of modern high speed systems like Wi-Fi (802.11a), LTE (Long Term evolution), DMT (Discrete Multi-tone Technique) systems, DVB (Digital Video Broadcast) systems. OFDM physical layer is also used for SDR (Software Defined Radio) based applications. In this paper a fast prototype design from concept to implementation of an OFDM system is carried out using Keysight Technologies Tool `SYSTEMVUE'. The implementation of final design was done in 40 nm CMOS Xilinx Virtex VI XC6VLX760 FPGA. The results obtained were analyzed on LA (Logic Analyzer) and were verified with the simulation results. Using SystemVue's model based FPGA flow rapid prototyping and high gain in design time can be achieved.
