Abstract: |
It is a multimedia information transmission time frequency matrix two-dimensional sub-channel dynamic alignment method, which belongs to digit information transmission technique field and comprises the following steps: to generate two-dimensional time zone and frequency zone matrix TFM channel alignment pattern according to certain rules; to align the multimedia program code flow input to the relative TDS-OFDM signal frame and OFDM sub-carrier wave according to the alignment pattern; to insert TFMp matrix information into the head frame group of TDS-OFDM; finally to send the complete signal of TDS-OFDM. |
