The optimal design of training sequences for Multiple-Input Multiple-Output(MIMO) channel estimation with spatial correlation is considered.Based on the criterion of Minimum Mean Square Error(MMSE)
the optimal training sequences that have controllable length are designed to exploit full information of the spatial correlation.Furthermore
a lower hound on the caparity of a training-based MIMO system is derived
from which the optimal number of training symbols is given.It is investigated that the proposed training sequences have good performance and the capacity lower bound is valid.
