摘要：
Motivated by the importance of multiple-input and multiple output line-of-sight communication in next generation backhaul networks, in this work we provide an overhead and performance comparison between time- and frequency-domain channel estimation in a bursty 2x2 LOS environment with single-carrier transmission and frequency-domain equalization at the receiver. For both types of channel estimation, analytical expressions for the weights of the involved equalizers are provided in the case of minimum-mean square error equalization. Finally, simulation results are provided regarding their error rate comparison and a discussion concerning their training overhead requirements.
