%X In this paper, the requirements of training sequence for channel estimation in SC-FDE systems are discussed, and the customarily used training sequence for channel estimation in OFDM systems can not be used in SC-FDE systems directly is pointed out. By analyzing, it is concluded that Newmann sequence is very suitable for SC-FDE systems. Without considering the energy lost of CP, the LS estimation performance bound is given. Theoretical analysis and simulation results show that this bound can be achieved by using Newmann sequence.
