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.

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 and arrangement for channel allocation in a radio communication system that uses a TD/CDMA subscriber separation method, an allocation of at least one channel is signalled to a radio station by an information element in a signalling message. At least one time slot is thereby selected by a time slot selection sub-information element. Subsequently, at least one CDMA code is selected for each selected time slot with a code selection sub-information element, whereby a number of code selection sub-information elements corresponds to a number of selected time slots.
