The Spatial Diversity Algorithm of Sampling Clock Synchronization in MIMO-OFDM Systems

Sampling offset estimation and sampling clock recovery are crucial in MIMO-OFDM systems. In this paper, a novel spatial diversity algorithm of sampling offset estimation in MIMO-OFDM systems is proposed. In addition, a lower complexity sampling clock recovery design is presented. The simulation results show that the proposed algorithm is accurate and robust against fast time-varying frequency-selective fading channel.
