Abstract :
In this paper, we propose a new rate-2, 2×2 spacetime block-code (STBC) with low complexity maximum likelihood (ML) detection. We focus on the operation under low signal-to-noise ratio (SNR) regions. Numerical results show that the proposed STBC outperforms the conventional rate-2, 2×2 STBC of WiMAX under low SNR regions. Also, the ML detection complexity of the proposed STBC is significantly reduced.
