摘要： Data symbols, transmitted by OFDM radio using at least two transmission antennae, are coded by a DSTBC coding and a DSTFBC coding. Two adjacent data symbols of a selected sub-carrier are provided for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers in the sub-carrier. The DSTFBC coding is carried out from the data symbols of the first sub-carrier direction. In each sub-carrier the two data symbols formed by DSTFBC coding are used for initializing a DSTBC coding in the OFDM symbol direction. In the reverse direction, two sequential DSTBC coded data symbols on a first sub-carrier for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers for DSTFBC coding from the data symbols of the first sub-carrier over the adjacent sub-carriers.

摘要： In an OFDM multi carrier modulation method, M sub-carriers are used in a frequency band of a broadband mobile radio channel and several symbols are used in a time band. With application of a MIMO multi-antenna method with T transmitting antennae and R receiving antennae, for all sub-carriers and all symbols, a single, pre-determined, channel-matched transmission strategy is used, which is described by a maximum of T*R complex values on the signal side, independent of the species of the MIMO multi-antenna method and independent of the size of the frequency/time bands.

摘要： In a communication system, a first transmitting station transmits a transmission signal to a first receiving station for transmitting a sequence of data via a radio interface. The radio interface is monitored with respect to an interference signal from an interference source prior to transmission via at least one of the first transmitting station and the first receiving station. The transmission only begins if the radio interface is sufficiently free from interference for a moment in time.
