Summary: | A data processing apparatus, a data processing method, and a program are disclosed. They improve communication performance by performing bit interleaving suitable for a modulation method that is a non-uniform constellation. One example of a data processing apparatus includes a mapping unit configured to generate a second bit sequence by mapping a first bit sequence to any symbol on a complex plane corresponding to a NUC modulation method, an inter-symbol interleaving unit configured to generate a third bit sequence by performing inter-symbol interleaving to the second bit sequence, an intra-symbol interleaving unit configured to generate a fourth bit sequence by performing intra-symbol interleaving for shifting M bits as a whole of the third bit sequence per a same number of M bits as the bit number M representing the symbol, and a modulation unit configured to wirelessly transmit the fourth bit sequence according to the NUC modulation method. |
