Optimizing Training-Based MIMO Systems: How Much Time is Needed for Actual Transmission?
2010 IEEE 71st Vehicular Technology Conference
We study the design of training-based multiple-input multiple-output systems in two block-wise transmission schemes. The conventional transmission scheme has a fixed amount of energy to be used in each block, hence transmission takes place in every block. For this scheme, we study the optimality of using all available time in each block for transmission and provide bounds to significantly reduce the ranges of the possible values of the optimal training and data lengths.
