A 1.2 Gbps Wireless LAN System for 4K Digital Cinema Transmission

摘要

Through this paper we propose a very high throughput (VHT) wireless LAN system based on IEEE802.11TGac's criteria. It attains throughput over 1.2Gbps for 100 feet propagation range by using 80MHz of bandiwdth on 5GHz band. 4 by 5 antennas configuration contribute 2"d-order diversity gain and maintain both the high throughput and the high performance. Greenfield format is employed due to its compact configuration to obtain the high throughput. Novel phase rotation are apllied to get low peak to average power ratio signal. 2 options of channel encoder, binary convolutional code and low density parity check code are available to enhance the performance. Run test for transmitting 4K digital cinema under modified channel model BTGn as a usage model proofs the excellent performance of the proposed VHT system.
