Abstract :
We propose a new space-time block code for three transmit antennas using a special modulation scheme, called "twin QPSK". This space-time block code has rate one and achieves significant diversity gain that is close to full diversity when used with "twin QPSK" modulation. The decoder detects the transmitted symbols in pairs. The performance of this space- time block code is compared with the performance of other space-time block codes. It is observed that this code achieves better performance than conventional space-time block codes.
