Abstract:
1. A signal processing method for transmitting data using a plurality of antennas in a mobile communication system, the method comprising: receiving transport block data; appending error correction bits to the transport block data; generating channel coded data from the transport block data appended with the error correction bits; performing spatial segmentation on the channel coded data to provide a plurality of spatially segmented data blocks; independently performing rate matching on each of the plurality of spatially segmented data blocks to generate a plurality of data streams and to provide a plurality of independent modulation schemes, wherein each of the plurality of independent modulation schemes corresponds to one of the plurality of data streams; independently performing modulation on each of the plurality of data streams by independently applying each of the plurality of independent modulation schemes to each corresponding data stream in the plurality of data streams; and independently performing physical channel mapping for each of the plurality of data streams to be transmitted to a receiving side via each of a plurality of physical channels, wherein the rate matching is performed after the spatial segmentation, and wherein the modulation is performed after the rate matching.
