摘要

在1.8GHz频段构建4G TD-LTE网络的电气无线网络中，正交频分复用(OFDM)和多输入多输出(MIMO)是关键技术。OFDM系统对载波频偏非常敏感，因此对OFDM系统进行准确的载波频偏估计至关重要。研究了多输入多输出(MIMO)正交频分复用(OFDM)系统中的载波频偏(CFO)问题，提出了一种多不变调频算法来估计MIMO-OFDM系统中的载波频偏。该算法利用了多不变性的特性。仿真结果表明，该算法具有比PM更好的CFO估计性能。

Multi-invariance propagator method-based carrier synchronization for MIMO-OFDM electrical special network

The electrical wireless network build 4G TD-LTE network in 1.8GHz band, orthogonal frequency division multiplexing (OFDM) and multiple input multiple output (MIMO) are the key technologies. The OFDM system is sensitive to carrier frequency offset (CFO) and hence accurate CFO estimates for the OFDM system are essential. In this paper, we study the problem of carrier frequency offset (CFO) in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems, and then a multi-invariance PM algorithm is proposed to estimate CFO in MIMO-OFDM system. The proposed algorithm employs the property of multi-invariance. Simulations show that the proposed algorithm has a better CFO estimation performance than PM.
