Description
In this paperg it is shown that orthogonal spaceytime block code zOSTBCg matrices designed for real signal transmission can be used for the transmission of complex signals when limited feedback bits are available from receiver to transmitterF This approach simplifies the maximum likelihood zMLg decoding at the receiver while making full rateg fully diversity transmission of complex signals possible using Q and w transmit antennasF Computer simulation results show that when sufficient feedback bits are usedg the proposed scheme provides comparable performance to those of the complex OSTBCs with higher decoding complexitiesF
