The exact pairwise error probability (PEP) of quasi‐orthogonal space–time block codes (QSTBCs) employing the power scaling technique in quasi‐static Rayleigh fading channels is derived. By utilising the derived PEP formula, the tight union upper bound on the bit error rate (BER) for the QSTBC with power scaling (PS‐QSTBC) is evaluated and compared with the Monte Carlo simulation results to verify the analytical results that full diversity rate‐1 transmission can be achieved. Furthermore, considering the closed‐loop system, the optimal value of the power scaling factor is also investigated in terms of minimising the union bound on the BER.
