For a multiple-input-single-output (MISO) communications system, we take the presence of the erroneous channel state information (ECSI) into consideration. multiple transmit antennas selection (TAS) over NUSO systems with space-time block coding (STBC) (TAS/STBC) is investigated, and a solution over order statistic characteristic of the selective channel with ECSI is proposed. A more accurate analytical expression of Chernoff upper bound (CUB) bit-error rate (BER) for Binary Phase-Shift Keying (BPSK) modulation is derived in flat Rayleigh fading channel. Finally, both CUB BER values and true BER ones with simulation show that TAS technique can improve obviously system transmission performance and mitigate effectively effects of the ECSI.
