A data processing apparatus to map input data symbols to be communicated onto sub-carrier signals of Orthogonal Frequency Division Multiplexed (OFDM) symbols. The number of sub-carrier signals available from each of the OFDM symbols being variable between OFDM symbols and the input data symbols include first sets of data symbols and second sets of input data symbols. The data processing apparatus includes a controller, an address generator, and an interleaver memory. The controller is configured, when operating in accordance with an even interleaving process to read out a first set of the input data symbols from the interleaver memory on to the sub-carrier signals of an even OFDM symbol using read addresses generated by the address generator, and to write in a second set of the input data symbols into the interleaver memory using the addresses generated by the address generator. |
