A design of next generation Gigabit MIMO wireless LAN system

This paper deals with a design of next generation Gigabit WLAN system based on IEEE802.11TGac's functional requirements. It achieves 1.1 Gbps throughput for 45 meter propagation distance with 80 MHz bandwidth on 5 GHz band. The proposed preamble ensures backward compatibility with the IEEE802.11a/n systems and has lower PAPR and comparable preamble efficiency with IEEE802.11n's preamble. It uses MIMO architecture to maintain both the high throughput and the high performance. Two options of channel encoder, binary convolutional code and low density parity check code are available to enhance the performance. Run test under in-door channel model demonstrates the excellent performance of the proposed system.
