On the Full-Rate Linear Complexity ۲×۲ Space-Time Block Code: Application in Keyhole Channels

In this paper, a new full rate, full diversity ۲۲ STBC with linear complexity in the receiver is introduced for keyhole channels, where the rank-deficiency of the channel matrix degrades system performance. This code is optimized based on the known criteria for these types of the channels. Simulation results demonstrate that the proposed code outperforms some of the well-recognized STBCs when BPSK and ۴-QAM constellation are utilized.
