Abstract: A data processing apparatus maps input symbols to be communicated onto a predetermined number of sub-carrier signals of an Orthogonal Frequency Division Multiplexed (OFDM) symbol. The data processor includes an interleaver memory which reads-in the predetermined number of data symbols for mapping onto the OFDM sub-carrier signals. The interleaver memory reads-out the data symbols on to the OFDM sub-carriers to effect the mapping, the read-out being in a different order than the read-in, the order being determined from a set of addresses, with the effect that the data symbols are interleaved on to the sub-carrier signals. The set of addresses are generated from an address generator which comprises a linear feedback shift register and a permutation circuit.

Abstract: A receiver for detecting and recovering payload data from a received signal comprises a radio frequency demodulation circuit, a detector circuit and a demodulator circuit. The radio frequency demodulation circuit detects the received signal. The received signal carries the payload data as OFDM symbols in one or more of a plurality of time divided frames, each frame including a bootstrap signal, a preamble signal and a plurality of sub-frames. The demodulator circuit detects bootstrap OFDM symbols to identify communications parameters for detecting the fixed length signalling data, detects the fixed length signalling data to identify the communications parameters for detecting the variable length signalling data, detects the variable length signalling data, and uses the fixed and variable length signalling data to detect the payload data.

Abstract: A transmitter transmitting payload data using OFDM symbols includes a frame builder configured to receive the payload data and to receive signalling data for use in detecting and recovering the payload data at a receiver, and to form the payload data and the signalling data into frames for transmission. A modulator can modulate a first OFDM symbol with the signalling data forming a first of the frames and modulate one or more second OFDM symbols with the payload data forming one or more other frames, and a transmission unit transmits the first and second OFDM symbols. The first OFDM symbol is combined before transmission with a signature sequence that can be configured to allow for detection of the first OFDM symbol at the receiver and decoding the signalling data before the one or more second OFDM symbols carrying the payload data and at lower signal to noise ratios.

Abstract: A receiver for detecting and recovering payload data from a received signal, the receiver comprising a radio frequency demodulation circuit configured to detect the received signal, the received signal carrying the payload data as Orthogonal Frequency Division Multiplexed, OFDM, symbols in one or more of a plurality of time divided frames, each frame including a preamble including a plurality of bootstrap OFDM symbols. One or more of the bootstrap OFDM symbols of the preamble carry signalling data represented as a relative cyclic shift of a signature sequence carried by the bootstrap OFDM symbols, the signalling data providing an indication of parameters for detecting and recovering the payload data carried by the one or more frames. The receiver comprises a detector circuit configured to detect and to convert a useful part of the one or more of the bootstrap OFDM symbols into the frequency domain and a bootstrap processor. The bootstrap processor is configured to generate, using the signature sequence, an estimate of a channel transfer function from a first bootstrap OFDM symbol, and to decode the signalling information carried by one or more other bootstrap OFDM symbols using the estimate of the channel transfer function and the signature sequence. A demodulator circuit is configured to recover the signalling data from the one or more bootstrap OFDM symbols using the estimate of the channel transfer function. The bootstrap processor is configured to generate, for each of the one or more other bootstrap OFDM symbols, an updated version of the channel transfer function, to equalise each of the one or more other bootstrap OFDM symbols using the updated version of the channel transfer function for each of the one or more other bootstrap OFDM symbols, and to detect the signalling data carried by the one or more other bootstrap OFDM symbols by correlating the equalised one or more other bootstrap OFDM symbols with a reproduced version of the signature sequence. Embodiments of the present technique provide an improvement in detecting and recovering signalling data carried by the bootstrap signals by updating the channel transfer function for each bootstrap OFDM symbols.

Abstract: A transmitter transmitting payload data using OFDM symbols includes a frame builder configured to receive the payload data, receive signalling data for use in detecting and recovering the payload data at a receiver, and form the payload data with the signalling data into transmission frames. A modulator is configured to modulate a first OFDM symbol with the signalling data forming a part of each of the frames and to modulate one or more second OFDM symbols with the payload data to form each of the frames. The transmitter combines a signature sequence with the first OFDM symbol, so that the first OFDM symbol can be detected within the frame before the second OFDM symbol. The transmitter includes a pilot signal inserter configured to insert a number of pilot symbols on selected sub-carriers of the first OFDM symbol sufficient to estimate a coarse frequency offset of the transmitted OFDM symbol.
