Abstract
A new diversity combining algorithm is presented in this paper with high performance in the STBC single carrier (SC) block transmission MISO system with two transmit antennas and one receive antenna. The decision on the transmitted signal is made by STBC-based SC frequency domain equalizer (STBC-SC-FDE), and then the line of sight (LOS) component under Rician fading channels or the component with highest power under Rayleigh fading channels in the received signal is obtained by cancelling the multipath signals reconstructed by the initial detecting solution and the channel impulse response (CIR) from the received signal. Then, the LOS or the strongest component is combined using STBC-like combining scheme. The new algorithm can achieve the performance advantages dramatically over STBC-SC-FDE which is verified by computer simulations carried out in the SUI-4 and TU wireless communication link.
