Abstract
A multiplexed space-time block coding (M-STBC) scheme is described that allows for transmitting a single multicast transmission in a heterogeneous MIMO (i.e., multiple-input and multiple-output) environment, where receivers with fewer antennas can receive a lower resolution version of the multi-cast transmission, while receivers with a greater number of antennas can receive a higher resolution version of the multi-cast transmission. Thus, the M-STBC scheme allows for transmitting the single multicast transmission that includes both a spatial multiplexing mode and a diversity mode.
