Channel Estimation Based on Complete Complementary Sequence for MIMO System
摘要
The novelty of complete complementary sequence (CC-S) is to improve the MIMO system performance utilizing complete orthogonality. What we proposed is the optimized design of implicit training sequence based on CC-S for MIMO wireless channel estimation. Channel estimation performance of MIMO system can be improved by resorting to the superior correlation of CC-S, including autocorrelation and cross-correlation. The method obtains the optimised implicit training sequences through an optimum training scheme with CC-S and the normalized mean square error (NMSE) of estimated channel matrix was analyzed. Simulation results demonstrate the performance improvements achieved by the proposed implicit training sequence algorithm. Furthermore, the feasibility of channel estimation based on CC-S for MIMO system is proved.
