Abstract: This paper presents Single-path Delay Feedback (SDF) architecture for implementing Fast Fourier Transform (FFT) for Multiple-Input Multiple-Output Orthogonal Frequency Division Frequency Multiplexing (MIMO-OFDM). The architecture of Single-path Delay Feedback and memory scheduling are the basic concepts used to implement the FFT processor with variable length. Depending on the SDF architecture, we implement the FFT processor-based design which is proposed in this paper. In this paper, we use MIMO-OFDM high data rates, high efficiency and high throughput. In this paper, we use radix-4 algorithm to implement the sequence because the speed of the operation is high. The functionality verification and the synthesis are carried out by using XLINIX.14.2.
Keywords: Single-Path Delay Feedback (SDF), Fast Fourier Transform (FFT), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiplexing (OFDM), Radix-4.
