Training Sequences Selection for Symbol Timing Estimation in Multiple Antenna Systems

摘要

In this paper, the problem of training sequences design for symbol timing estimation in MIMO channel is addressed The optimal training sequences are derived by minimizing the modified Cramer-Rao bound (MCRB) with respect to the training data. It is found that when the transmit pulse is a root raised cosine pulse, the optimal training sequences resemble the Walsh sequences.
