This paper presents the average capacity and error performance of 3×4 orthogonal space time block code (OSTBC) and transmits antenna selection (TAS) with multiple antennas. In TAS scheme, we consider one transmit antenna is selected for transmit signals at the secondary transmitters and the secondary receiver applies the maximum likelihood (ML). In 3×4 OSTBC scheme, we consider three transmit antennas and four receive antennas. The experimental results shown that the average capacity and bit error rates are better performance of 3×4 OSTBC is comparing to TAS scheme.
