摘要:
文中设计实现了一个 OFDM 基带信号处理系统,该设计利用 FPGA 的可重构性与灵活性,采用基于 CORDIC 算法流水结构高速浮点蝶形运算单元的 FFT 专用处理器,以及在自适应调制模式下的增强调制方式(64-QAM)来实现信号的调制,具有较高的传输速率.系统设计合理利用 FPGA 资源,高度集成在一个 FPGA 芯片内,简化了系统的复杂度;并最终适配到 Altera 的 EP2C20F484C6芯片上,可稳定运行在100 MHz 的时钟频率下;同时该系统具有较高的灵活性与通用性,且结构简单,杂波抑制性好,因此具有一定的应用前景
Abstract:
It designed an OFDM baseband signal processing system. This design used FPGA reconstruction and flexibility,FFT dedicated processor based on high speed floating point butterfly operation unit of CORDIC algorithm flow structure,as well as enhanced modulation mode (64-QAM) in adaptive modulation mode to realize the signal modulation,has the high transmission rate. The System design rea-sonably used FPGA resources,highly integrated in a FPGA chip inside,simplified the complexity of the system,and finally adapted to the EP2C20F484C6 Altera on a chip,stable operation in 100 MHz clock frequency. At the same time,this system has high flexibility and uni-versality,and simple structure,clutter suppression is good,as a result this has a certain application prospect
