DSP Design of Channel Estimation in MIMO-OFDM System
In this paper, the simplified DSP implementation of training sequence-based on Least Square (LS) channel estimation in MIMO-OFDM system was demonstrated. A proper design of the training sequence not only simplifies channel estimation, but also still obtains the best estimation performance. For the purpose of getting channel estimation algorithm to work in real time, some main approaches are carried out to speed up operation, saving memory and improving accuracy. Statistics on resource occupation and running time of such a scheme in TMSC6416 chip was given. While the implementation is applicable in B3G MIMO-OFDM system, which adopted 4 transmit antennas and 8 receive ones.
