A pilot pattern based algorithm for MIMO-OFDM channel estimation

摘要

An improved pilot pattern algorithm is proposed in this paper that could facilitate channel estimation in terms of MIMIO-OFDM system. The proposed algorithm is a configuration of the analysis of LS that is readily a STBC formatted algorithm in specific for the channel estimation in terms of the pilot-based MIMO-OFDM. Simulations in this paper have show that this algorithm can perform better than the classical counterparts which intend to be borne with the single symbol scheme. It is also proved that the algorithm for the doubled symbols scheme can achieve almost the same performance with only half of the complexity.
