摘要： 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.

摘要： Interleaving aspects in the case of Signal Space Diversity (SSD) are considered here, in particular when the SSD transmission is expected to be overlapped by a colliding non-orthogonal Ultra Reliable & Low Latency Communication (URLLC). The interleaver's depth when interleaving I and Q components of a rotated modulated symbol is chosen such that a gap of at least an expected maximum size, measured in transmission units, of a possible colliding wireless signal, is generated between a respective In and Qn component of a same symbol n.

摘要： A receiver detects and recovers payload data from a received signal. The receiver comprises a radio frequency demodulation circuit configured to detect and to recover the received signal, the received signal having been formed and transmitted by a transmitter to carry the payload data from a plurality of different channels as Orthogonal Frequency Division Multiplexed (OFDM) symbols in one or more of a plurality of transmission frames, each of the transmission frames comprising a frame synchronisation OFDM symbol, followed by one or more primary signalling OFDM symbols, then one or more secondary signalling OFDM symbols followed by one or more payload OFDM symbols. The frame synchronisation OFDM symbol and the one or more primary signalling OFDM symbols have been modulated with a signature sequence, the signature sequence of the one or more primary signalling OFDM symbols having been cyclically shifted with respect to each of a preceding one of the frequency synchronisation OFDM symbol or the one or more primary signalling OFDM symbols, with the cyclical shift primary signalling data carried in the one or more primary signalling OFDM symbols. The receiver further comprises a Fourier transformer configured to convert successively a temporal length of a useful part each of the frequency synchronisation OFDM symbol and the one or more primary signalling OFDM symbols into the frequency domain, a multiplier configured to receive each of the frequency domain samples of a current one of the primary signalling OFDM symbols and to multiply each sample with the conjugate of a corresponding sample of one of the frame synchronisation OFDM symbols or one of the one or more primary signalling OFDM symbols immediately preceding the current one of the primary signalling OFDM symbols to produce for each sub-carrier sample an intermediate sample, an inverse Fourier transformer configured to convert the intermediate samples resulting from the current one of the primary OFDM symbols into the time domain, and a cyclic shift detector configured to estimate the primary signalling data conveyed by each of the one or more primary signalling OFDM symbols by detecting a cyclic shift of the signature sequence present in each of the one or more primary signalling OFDM symbols from a peak of the time domain intermediate samples.

摘要： 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 equalize 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 equalized 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.

摘要： An arrangement for detecting signaling data from bootstrap Orthogonal Frequency Division Multiplexed (OFDM) symbols in the frequency domain, which can provide a more accurate estimate of the signaling data than other arrangements that operate in the time domain. The arrangement includes detecting a cyclic shift of a signature sequence, which has been applied to represent the signaling data, as an average phase change between each of the sub-carriers of the bootstrap OFDM symbol. As a result the signaling data can be more accurately detected or detected at lower signal to noise ratio.

摘要： An apparatus and a corresponding method for mapping payload data of mapping input data streams onto a mapping output data stream having a channel bandwidth for transmission in a multi-carrier broadcast system includes first and second frame forming mechanisms. The first frame forming mechanism is adapted to form first frames having a first frame structure and the second frame forming mechanism is adapted to form second frames having a second frame structure. Preferably, in a second frame structure the data blocks of a particular mapping input data stream are spread in time and frequency over various data symbols and various data segments of the second frames to provide high robustness against disturbances. The payload portion of the second frame is preferably segmented into various data segments enabling use of a narrow-band receiver, even if both the first and second frames cover the same total channel bandwidth.
