OFDM 통신 시스템을 위한 신호처리 하드웨어 플랫폼 개발

초록

In this paper, an efficient hardware platform for the digital signal processing for OFDM Communcation systems is presented. The hardware platform consists of a single FPGA, two DSPs with 8000 MIPS of maximum at 1 ㎓ clock, 2-channel ADC and DAC supporting maximum 125 ㎒ sampling rate, and flexible data bus architecture, so that a wide variety of baseband signal processing algorithms for practical OFDM communication systems may be implemented and tested. The IEEE 802.16 software modem is also presented in order to verify the effectiveness and usefulness of the designed platform.
