Data frame forming method and corresponding interleaving and encoding modulation method

The present invention relating to a new method of data frame framing and the corresponding method of interleaving and coding modulation are suitable to be used for compatible transmitting of stationary receiving, portable and mobile receiving. The system uses the block interleaver with the interleaving depth of 50 or 51 to carry out the interleaving. According to the different application purpose, the coding modulations of 16 QAM+3/4 cellular coding, 64 QAM+5/6 cellular coding, 256 QAM+7/8, QPSK or QPSK+1/2 cellular coding will be used to carry out the coding for the data transmitting and to use new type framing method to framing and transmitting in data frame unit.
