Abstract

Provision of high data rate services on train has attracted a great attention recently. To evaluate the improvement of route-tracking beamforming over high-speed railway communication system, a low-complexity platform was proposed and experiments were carried out over Taiwan High Speed Railway (THSR) train. With Global Positioning System (GPS) information feedback and antenna direction adjustment the received signal strength indicator (RSSI), Carrier to Interference-plus-Noise Ratio (CINR), throughput and cell coverage were improved. Also the influence over path loss model and Transmission Control Protocol (TCP) throughput behavior were analyzed. To conclude, this research provides evaluation steps and analysis reference for deploying route-tracking beam-forming technology over high-speed railway communication system
