Abstract :
Recently, we proposed a multi-block frequency-domain equalization (MB-FDE) for single-carrier space-time block coded time-division duplex (SC-STBC TDD) transmission. In this paper, we propose an adaptive two-dimension (2D) multi-input multi-output (MIMO) channel estimation (CE) for SC-STBC TDD transmission in a high mobility environment. In the proposed adaptive 2D-MIMO-CE, the channel over consecutive data blocks is directly estimated by using jointly optimized multiple 2D filters, each associated with each pilot block, based on minimum mean square error (MMSE) criterion. We evaluate, by computer simulation, the BER performance when using SC-STBC TDD transmission with MB-FDE and the adaptive 2D MIMO-CE and showed that the adaptive 2D MIMO-CE can achieve better BER performance than when using MMSE-CE and MMSE prediction.
