【摘要】 针对中国标准地面数字电视(DTMB)系统,提出了一种3 780点FFT处理器的复用结构设计方法。采用流水线结构,对3 780点进行层层分解,并在DTMB系统中充分复用该处理器的设计。仿真表明,该设计大大降低了所需逻辑资源,适用于符合国家标准要求的调制与解调系统。更多还原

【Abstract】 This paper presents a reusable design of 3780-point FFT processor for Digital Terrestrial Multimedia/Television Broadcasting(DTMB) system.The processor adopts pipeline structure,decomposes 3780-point down to every level and reuses the design of the processor fully in the DTMB system.According to the software and hardware simulation,this design has greatly reduced resources required for the logic applies,it’s applicable to the requirements of national standard modulation and demodulation system.更多还原
