  • Method and transmitter for transmitting data in a multi-carrier system via a number of transmitting antennas
    Patent number: 8111660
    Abstract: A method transmits data by radio during which a frequency band is split into a plurality of subcarriers, and a plurality of antennas are used for transmitting. The data are split into a number of elements, which are to be respectively transmitted by each antenna, said number of elements corresponding to the number of subcarriers, whereby for each antenna, each element is respectively assigned to a subcarrier for transmitting, and at least two antennas on at least one subcarrier transmit different elements. Before an OFDM modulation for each antenna, each element is multiplied by an antenna-specific and element-specific factor. Alternatively, after an OFDM modulation for at least one antenna, the time sequence of the time-dependent signal generated on the basis of the OFDM modulation is reordered. A transmitter carries out the method.

  • Holding device for cargo
    Publication number: 20070207000
    Abstract: A holding device for cargo in the trunk or storage compartment of passenger cars. The holding device includes a base part that can be selectively positioned and retained in a tie-down rail mounted in the storage compartment. Securing means in the form of a pivotable flap is provided which is spring-biased such that stored cargo can be pressed by the flap against a side wall of the trunk or the rear back seat and cannot be slung back or forth due to forces occurring during driving.
