Abstract:
1. A method for implementing spatial data processing with unequal modulation and coding schemes (MCSs), the method comprising: generating a first spatial stream and a second spatial stream; performing a space time block coding (STBC) processing on the first spatial stream to generate two STBC-processed data streams; performing a cyclic delay diversity (CDD) processing on the second spatial stream; and transmitting simultaneously the STBC-processed data streams and the CDD-processed second spatial stream in parallel with at least three antennas, the STBC-processed data streams being transmitted via at least two antennas, respectively, and the CDD-processed second spatial stream being transmitted via at least one additional antenna, wherein an MCS is selected for each spatial stream independently of the other spatial stream and each of the spatial streams is modulated with the selected MCS for each spatial stream.
