Abstract	In this paper, we present a 4×4 MIMO-OFDM system for wideband video transmision. This video transmission system is modified from the DVB-T system by including the MIMO technique and a proposed LLR-based adaptive hierarchical modulation involving channel SNR and H.264/AVC packet priority. In the proposed system, Reed-Solomen encoder packet format, inner interleaver structure and pilot pattern are designed for the adaptive hierarchical modulation and the MIMO-OFDM transmission. The proposed system can transmit at least four H.264/AVC streams at the same time and possesses high noise tolerability. Finally, we also design and develope an FPGA plateform to emulate its feasibility and the hardware capability. The FPGA system runs at 48MHz and achieves 20Mbps∼40Mbps throughput in 2×2 MIMO-OFDM transmission scheme at 6MHz bandwidth.
