- W2393019546 abstract "In the practical physical environments,to a large extent,the accuracy of channel estimation is influenced by the channel correlation estimation.Aiming at MIMO-OFDM system,the idea of channel sounding that sending sounding signal before data transmission was introduced,and the joint estimation of the channel and its correlation were done based on the relationship between the correlation matrix of the received signal and that of the channel.Meanwhile,the correlation matrix of the channel gained from the channel sounding could be used to assist the system to do the channel estimation as a known condition during the data transmission.Theory analysis and simulation results show that this algorithm guarantees the accuracy of the channel estimation when the channel space correlation can not be ignored,that the estimation algorithm based on signal processing will not increase the complexity of the algorithm,that it doesn't occupy the system bandwidth during data transmission using the idea of channel sounding,and that this algorithm has the most application value in practice." @default.
