Apparatus and method for data transmission in a multi-input multi-output radio communication system
摘要
The input signal (IN) enters a series-parallel converter (SPW). Data strings (D11-D1MT) are passed through sub- channels (SU11-SU1MT) to modulators (QMOD1-QMODMT). Signals (DF11-DF1MT) leave the modulators and pass to a matrix filter (MF). Signals (DZ11-DZ1MT) are transmitted from radio antennas (A11-A1MZ) and are picked up by receiver antennas (A21-A2MR). Signals (n) may be mixed with the received signals to produce signals (DZ21-DZ2MR) fed to a detector (DETZ). Signals (D21-D2MT) pass through sub-channels (SU21-SU2MT) to a parallel-series converter (PSW) which produces the output signal (OUT).
