Abstract
A phase-shift based pre-coding scheme used in a transmitting side and a receiving side that has less complexity than those of a space-time coding scheme, that can support various spatial multiplexing rates while maintaining the advantages of the phase-shift diversity scheme, that has less channel sensitivity than that of the pre-coding scheme, and that only requires a low capacity codebook is provided.

14. An apparatus to perform downlink baseband signal generation for a multiple antenna system with multiple antenna ports, the apparatus comprising:
-
a layer mapper that performs layer mapping of complex-valued modulation symbols for each code word to be transmitted; a precoder that performs a precoding procedure on a first set of complex-valued modulation symbols received from the layer mapper to generate a second set of complex-valued modulation symbols to be mapped onto resources related to the antenna ports; and a transmitter that performs signal transmission via the antenna ports based upon the second set of complex-valued modulation symbols generated by the precoder. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
