Review of MIMO-OFDM using Carrier Offset on behalf of Literature Survey

Abstract

In this paper, proposed a joint estimation of Carrier Frequency Offset (CFO) and Channel Distortion for Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system using training sequences. Since the main objective of maximizing the sum of rates of all the nodes in the network can lead to a severe bias in rate allocation among the nodes. An important technique for an OFDM system is IFFT (Inverse Fast Fourier Transform) and FFT (Fast Fourier Transform) which is used for modulation and demodulation of OFDM systems. Carrier Frequency Offset (CFO) acquisition algorithm and Carrier Frequency Offset (CFO) tracking algorithm are proposed to improve the estimation accuracy of MIMO OFDM system. The proposed estimation method requires at least one OFDM training block for estimation and training symbols should be random Joint Estimation of Carrier Frequency Offset (CFO) and Channel Distortion Using Two Repeated Training Sequences m. If the OFDM training block consists of two repeated sequences, a low complexity two step approach used to solve any one of the two problems and important insights can be obtained by Inferring duality results for the other problem.
