摘要:
An apparatus for determining a target precoding matrix from a plurality of precoding matrix candidates is provided. The apparatus includes a covariance matrix value provider, a real part determiner and a precoding matrix determiner. The precoding matrix determiner is adapted to determine the target precoding matrix from the plurality of precoding matrix candidates, wherein the precoding matrix determiner is configured to determine the target precoding matrix based on at least one of the one or more real covariance values.
摘要:
An apparatus for decoding a received signal is provided. The received signal has been transmitted by conducting a transmission. The apparatus for decoding includes a detector and a filter application unit. The detector is configured to detect whether the transmission is a SU-MIMO transmission or a MU-MIMO transmission. The filter application unit is configured to apply either a first receive filter or a second different receive filter on the received signal depending on whether the transmission is the SU-MIMO transmission or the MU-MIMO transmission.

摘要:
In a method for sending communication signals, space-time block coding is performed by dividing a data stream of complex-value data symbols into a number KT>2 of partial data streams of respectively n>2 data symbols. the data symbols in the partial data streams are used to form n×KT matrix CKT. Transmitter-end predistortion is performed by using the matrix CKT to form a matrix D, and the data symbols are sent by KT transmission antennas according to their arrangement in the matrix D.
