Abstract
Recently, the statistical properties of the equivalent channel representation of a multipleinputmultiple output (MIMO) system employing rate one quasiorthogonal spacetime block codes (QSTBC) for n(T) = 2(n), n >= 2 transmit antennas was characterized. It was shown, that these QSTBC were capable of achieving a significant fraction of the outage mutual information of a MIMO system. In this letter, based on the Minkowski's determinant inequality and the Meijer's Gfunction we derive an upper bound for the fraction of outage probability achieved with QSTBC for the general case of n(T) = 2(n), n >= 2 transmit antennas. Simulations results show that this bound gets tight for all signaltonoiseratios (SNR) values by increasing the number of receive antennas.
