摘要： In order to permit and already occupied frequency spectrum to be utilized for the radio transmission of a data stream without interfering with the services already established there, a plurality of the RF carriers modulated with the data stream are either transmitted in the frequency gap between two adjacent frequency FM services at the same location or in the free frequency ranges at both sides of an FM service, while leaving out its rated frequency occupation. Compared to the level of the RF carrier of the adjacent frequency FM service or the FM service in the middle, the level of the plurality of RF carriers is selected to be sufficiently low in the sense of a signal to noise ratio that is sufficient for FM reception of the FM service or services. Moreover, the mentioned level is selected to be sufficiently high in the sense of noise immunity against locally remote FM services which fall into the frequency range or frequency gap intended for the transmission of the plurality of RF carriers. The data stream modulating the RF carriers is provided with increased error protection in the sense of providing sufficient noise immunity against the adjacent frequency FM service or services or the FM service or services in the middle.

摘要： In a digital audio-signal transmission process, digital audio signals are coded in sub-bands. One or more scaling factors are determined for each sub-band. The coded signals and scaling factors are transmitted in data blocks, then decoded and reproduced at a receiver. The data block contains several types of information including a header, error processing information, a CRC (cyclic redundancy check) protection word, audio information including a bit allocation table, scaling factor selecting information, one or several scaling factors per transmitted sub-band, filler bits, and supplementary information with audio-signal-dependent supplementary information. To improve the protection of the above-described sub-band coded audio signals against transmission errors, supplementary error protection information or an error protection bit is added to the data block instead of filler bits, in order to protect the scaling factors. Acoustically uncomfortable play-back disturbances caused by scaling factor errors are thus eliminated. The invention may be used in digital audio broadcast (DAB), DAB-receivers, recorders and play-back systems.
