This paper investigates the performance of an Alamouti coding based transmit diversity scheme with multiuser max-scheduling in spatially correlated channels. An exact closed form of ergodic capacity is derived, and bit error rate (BER) analysis is performed with a log likelihood radio (LLR) approach for two transmit antennas case. Our analytical and numerical results verify a positive effect of spatial...
This paper introduces an efficient multiple-decision-feedback (MDF) detection for space time block code (STBC) over time-selective fading channels. The MDF detection performs several decision-feedback (DF) detections for the most probable points obtained by a log-likelihood ratio (LLR) based bit flipping scheme. Simulation results show that, with reasonable complexity, the MDF detection provides near...
