    Abstract: A transmitter transmits data using Orthogonal Frequency Division, OFDM, symbols. The transmitter comprising a forward error correction encoder configured to encode the data to form forward error correction encoded frames of encoded data cells, a service frame builder configured to form a service frame for transmission comprising a plurality of forward error correction encoded frames, a convolutional interleaver comprising a plurality of delay portions and configured to convolutionally interleave the data cells of the service frames, a modulation symbol mapper configured to map the interleaved and encoded data cells of the service frames onto modulation cells, and a modulator configured to modulate the sub-carriers of one or more OFDM symbols with the modulation cells. A controller is configured to form signalling data to be transmitted to include an indication of an identified first cell of a first of the forward error correction frame of a new service frame which can be decoded from cells received from the new service frame or the new service frame and one or more service frames following after the new service frame. By detecting the first cell of a first of the error correction encoded frames of a new service frame which does not have any data cells in one or more previous service frames as a result of the convolutional interleaving then a receiver, which has acquired the new service frame but none of the one or more previous service frames can decode this first forward error correction encoded frame of the new service frame and ignore the other forward error correction encoded frames earlier in the service frame. Therefore for example a receiver may power on or channels during a previous service frame and be directed to only decode a forward error correction encoded frame that it can decode.

    Abstract: A method for processing a plurality of received copies of the same original data, the method comprising performing maximum ratio combining on equivalent data portions of the received copies to derive at least one further equivalent data portion. The received and the constructed copies are then divided into sub-portions and combinations of divided sub-portions are assembled to provide reconstructed data portions. An error rate assessment is performed on the reconstructed data portions; and on this basis one is selected as an output.
