The performance may be reduced by the path between transmission and reception in a bad state in wireless communication systems using space-time codes(STCs).An STC called multi-rate linear dispersion codes(LDC) is proposed and analyzed, and its BER performance is a good trade-off between classical LDC and LDC-TAS. A design of multi-rate LDC based on extended matrix method is given. Further, an algorithm of adaptive transmit antenna selection(A-TAS) with multi-rate LDC is proposed, and it has better performance than classical LDC-A-TAS.
