摘要： In a transmitting/receiving concept a redundancy-adding encoder with a code rate larger or equal 0.5 is used in order to obtain two data streams for two different transmitters which are arranged at spatially different positions. Both transmitters transmit in the same frequency band. In the receiver, the receiving signal is sampled by a first sampler synchronous to the first transmitter and is output by a second sampler synchronous to the second transmitter in order to obtain a first and a second receiving signal which are fed to a trellis decoder in order to obtain a decoded first and second receiving subgroup of code units which are again fed to a calculating means in order to calculate the interference signals which are then combined with the corresponding receiving signals for an interference reduction. The iterative concept enables an interference reduction for receiving signal generated by two spatially separated transmitters which are transmitting in the same frequency band, however. The receiver concept shows a quick convergence and thus enables the two transmitters to transmit in the same frequency band, which results in a reduction of the required bandwidth by half compared to a corresponding transmitter concept in which the first and the second transmitters transmit at different frequencies.

摘要： In a coding method and a coder for introducing a non-audible data signal into an audio signal, the audio signal is first transformed to a spectral range and the masking threshold of the audio signal is determined. A pseudo-noise signal and a data signal are provided and multiplied with each other so a to provide a frequency-spread data signal. The spread data signal is weighted with the masking threshold, and thereafter the audio signal and the weighted data signal are superimposed. In a method and a decoder for decoding a data signal introduced into an audio signal in non-audible manner, the audio signal is first sampled and thereafter the sampled audio signal is filtered in non-recursive manner. The filtered audio signal is subsequently compared to a threshold value so as to retrieve the data signal.

摘要： The inventive concept enables backward-compatible extension of existing interleaver-based transmission systems to the effect that in addition to an existing logical transport channel, which is interleaved using a standardized interleaver profile, further logical transport channels may be transmitted via the same physical transmission channel. In this context, the first transport channel obviously is reduced in terms of data rate, so that the additional transport channels may actually obtain a transmission capacity that is needed accordingly. Interleaver profiles of the further logical transport channels are derived, to this end, from the interleaver profile of the first transport channel.

摘要： A convolution interleaver for processing a codeword derived from an input block of symbols using a redundancy-adding coding, and having more symbols than the input block, wherein the codeword has a sequence of interleaving units, wherein each interleaving unit has at least two symbols, includes an interleaver. The interleaver changes the sequence of interleaving units to obtain an interleaved codeword having a changed sequence of interleaving units. In particular, the order of the symbols within an interleaving unit is not changed by the interleaver. The order of the interleaving units in the codeword among each other or with respect to a previous or subsequent codeword is changed, however.

摘要： A method and apparatus provide coarse frequency synchronization compensating for a carrier frequency deviation from an oscillator frequency in a demodulation system capable of demodulating a signal having a frame structure with at least one useful symbol and a reference symbol which is an amplitude-modulated sequence. A received and down-converted signal undergoes amplitude-demodulation to generate an envelope that is correlated with a predetermined reference pattern to determine the carrier frequency deviation. Finally, the oscillator frequency is controlled based on the carrier frequency deviation. The reference symbol may comprise two identical sequences. In this case, the envelope obtained by the amplitude-demodulation has two portions which are based on the identical sequences. One of the portions of the envelope is correlated with the other one of the portions in order to determine the carrier frequency deviation. The oscillator frequency is controlled based on the determined carrier frequency deviation.
