摘要
本文研究了基于IEEE802.16a的OFDM基带调制系统的实时实现,提出了一种切实可行的IEEE802.16a的OFDM调制方式的FPGA实现方法与结构,并介绍了IFFT运算、QPSK映射和插入循环前缀的具体电路。最后给出了硬件性能分析。
The implementation of the OFDM baseband modulation system based IEEE 802.16a standard is studied.An OFDM modulation structure based on FPGA is presented and the circuits of IFFT,QPSK mapping and Cyclic Prefix inserting are also addressed.Finally,the performance analysis of the hardware is given.
