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 MIMOOFDM 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.

Highlights

  • Fast Fourier Transform (FFT) is mostly used for many applications

  • We evaluate the Discrete Fourier Transform (DFT)

  • FFT is the main block in Orthogonal Frequency Division Multiplexing (OFDM) as it deals many operations to be done

Summary

INTRODUCTION

Fast Fourier Transform (FFT) is mostly used for many applications. Among many communication applications digital signal processing is one which uses Fast Fourier Transform. Decimation in time and Decimation in frequency are two different ways to perform Fast Fourier Transform. When FFT is combined with MIMO we get the results at high speed. By using the combination of MIMO-OFDM with FFT the results are getting a very fast manner, high reliability, high efficiency and high throughput. For these reasons we use a combination of FFT with MIMO-OFDM. Pipelined architectures helped in a better way for the implementation of FFT
