In this paper, we present transmit antenna selection (TAS) for wireless communication systems with space-time block codes (STBC). In coherent STBC systems, channel estimation is necessary at the receiver for decoding. In the proposed scheme, the transmitter selects the one or several antennas with best estimated channel gain for STBC transmission. Exact closed-form bit-error probability expression is derived for two specific scenarios. The TAS systems achieve full diversity provided by the total number of transmit and receive antennas.
