Abstract :
This paper investigates the hardware and architecture requirements for an OFDM adaptive modulation system. The hardware modules for a baseband adaptive uncoded OFDM transmitter, receiver and feedback link have been implemented on an FPGA. This system is used for fast hardware-in-the-loop simulation when combined with the implementation of a wireless channel model. It is also demonstrated that one high-end FPGA chip can provide all the resources necessary for the implementation of the system.
