Abstract

In practical wireless communication systems, the number of the receive antenna is more restricted than that of the transmit antenna. Spatial division multiplexing (SDM) technique normally imposes a restriction that the number of receive antenna should be more than or equal to that of transmit antennas whereas the space time coding (STC) technique can be adopted without such a limitation. The hybrid STBC scheme is a mixture of the above two systems. We propose two approaches to improve the hybrid STBC scheme:a precoding method and a decision feedback detection. Applying a linear precoding matrix with full rank property can improve the performance. Also, the decision feedback detection scheme cancels out the interference using already-detected components. Simulation results show that the proposed methods outperform the conventional hybrid STBC detection algorithm for frequency selective channels and its gain increases for higher modulation level.
