In this paper the design of 128/64 point Fast Fourier Transform Processor (FFT Processor) is proposed to support future generation Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO OFDM) based IEEE 802.11n wireless local area network base band processor. The pipelined Mixed Radix Multi-path Delay Feedback (MRMDF) FFT architecture is proposed to provide a higher throughput rate combining the characteristics of both Single-path Delay Feedback (SDF) which is used to reduce memory size and Multi-path Delay Commutator (MDF) by using the multi-datapath scheme. That is higher throughput rate can be provided by using four parallel data path.
