Abstract

A field programmable gate array (FPGA)-based hardware/software co-verification scheme is proposed for the design of orthogonal frequency-division multiplexing (OFDM) baseband systems. It provides a platform to simulate the software implementation and verify the hardware implementation of a baseband OFDM system. The baseband system is divided into two partitions implemented by software and hardware respectively. User datagram protocol (UDP) is used for data transmission to connect these two partitions via Ethernet, and hence integrates the complete baseband system. A radio-frequency (RF) front-end is also provided to modulate baseband signals and demodulate RF signals. Therefore, the software simulation in the testbed is running over real wireless channels, which can verify the correctness of the algorithm. On the other hand, the hardware implementation can be verified by software processing in real time, which makes the fault localization more efficient. An example of equalizer design is introduced to illustrate the effectiveness of the proposed testbed.
