MIMO-OFDM的FFT/IFFT处理器

摘要

This paper presents a configurable FFT/IFKT processor oriented to Multiple Input Multiple Output(MIMO) Orthogonal Frequency Division Multiplexing(OFDM). It gives the pipelined architecture, introduces one data reordering module to deal wilh 4 multiple data sequences, with different rate. Performance analysis shows that the processor is designed in SMIC 0.13 μm technology with the core size of 1.800×1.500 μm2.%面向多输入多输出(MIMO)正交频分复用(OFDM)系统,设计一种可配置的FFT/IFFT运算处理器.给出多通路流水线FFT/IFFT处理器架构,通过一个输入数据重排模块,实现来自4条信道的多通蹄数据同时计算,支持小同数据率的FFT/IFFT运算.性能分析表明,在SMIC 0.13 μm工艺下,该处理器的最高时钟频率可达125 MHz,面积达到1.800×1.500 μ m2.
