APSIPA ASC 2009: Asia-Pacific Signal and Information Processing Association, 2009 Annual Summit and Conference. 4-7 October 2009. Sapporo, Japan. Oral session: Wireless Communications (7 October 2009).

We propose an over 1.2 Gbps throughput wireless LAN system based on IEEE802.11TGac's requirements. It reaches 33 meter propagation distance by using 80MHz of bandiwdth on 5GHz band. 4×5 antennas configuration contribute 2nd-order diversity gain and maintain both the high throughput and the high performance. The proposed Greenfield format preamble has high preamble efficiency. Novel phase rotation is employed to get low PAPR signal of preamble and data fields. 3 different coding rates are examined for 64-QAM constellation which all accomplish over 1 Gbps with maximum throughput 1.266 Gbps. Run test for transmitting 90 frames of 4096×1714 pixels/frame digital cinema under in-door channel model proves the excellent performance of the proposed system.
