| Abstract: | We must have a good knowledge of the channel character of DTTB to design optimum the systemof DTTB. Based on the results of the channel estimation and equalization for OFDM system,a channel mod-el of DTTB system is established in this paper. At the same time,a method of abstracting the information ofCSI is introduced. |
