    摘要: In the novel method for data transmission via a radio interface in a radio communications system, at least two data channels are assigned to one connection. Each data channel can be distinguished by an individual spread code. In addition to data symbols, midambles with known symbols are transmitted in a data channel. The number of midambles being used for the connection is less than the number of data channels. The method is particularly suitable for use in TD/CDMA 3rd generation mobile radio networks.

    摘要: In a method for data transmission in a radio communications system, a radio interface is subdivided into time slots for a transmission of bursts. In this case, the data are transmitted in data channels in a time slot, in which data channels can be distinguished by use of individual spread codes. A finite burst containing data symbols and at least one midamble with known symbols is used for data transmission in a data channel. At least one parameter is determined for the traffic conditions of the radio interface, and a ratio of a length of the midamble and a data part with data symbols is adjusted depending on the traffic conditions. The method is suitable in particular for use in 3rd generation TD/CDMA mobile radio networks.

    摘要: Data is transmitted via a radio interface in a radio communications system in that at least one subscriber signal is transmitted, which has an individual fine structure applied to it and, in addition to data symbols in data sections, contains a midamble with known symbols. The fine structures of the data sections and of the midamble differ. At the transmission end, a sum signal is produced which contains signal sections to which different fine structures are applied. The sum signal is filtered in at least one transmission filter and is transmitted via a transmission channel to a receiving radio station. A control device controls the addition so that different attenuation of the signal sections is compensated for by the filtering. The method is suitable, in particular, for mobile stations having a single or variable data rate, and for base stations for use in 3rd generation TD/CDMA mobile radio networks.

The single-carrier signals are then combined to form a crest factor reduced multi-carrier signal. A corresponding circuit and corresponding computer program product useable during manufacture and operation are also disclosed.

    摘要: A method for crest factor reduction of a multi-carrier signal is disclosed. The multi-carrier signal comprises a plurality of single-carrier signals, each single-carrier signal having signal-specific spectral properties. The method comprises identifying a peak in the multi-carrier signal and a time of occurrence of the peak and generating a plurality of cancellation pulses depending on the time of occurrence of the peak. A particular cancellation pulse of the plurality of cancellation pulses is associated with a particular single-carrier signal and cancellation pulse-specific spectral properties of the particular cancellation pulse substantially match the signal-specific spectral properties of the associated particular single-carrier signal. The method further comprises combining the plurality of cancellation pulses to form a combined cancellation pulse and applying the combined cancellation pulse to the multi-carrier signal to reduce the peak. A corresponding circuit and corresponding computer program products useable during manufacture and operation are also disclosed.
