Abstract :
In this paper, we introduce a physical layer implementation and some test results for the multiple input multiple output - orthogonal frequency division multiplexing (MIMO-OFDM) fast prototype system for the fourth generation mobile communication. The system has the key features of antenna diversity maximizing and fading-robustness with the preamble/pilots and frame structures, which are suitable for channel estimation, timing, and frequency synchronization and unbiased signal-to-noise-plus-interference ratio estimation. These features are verified by the analysis and evaluation test results got from the implemented MIMO-OFDM system.
