DOPPLER-NULLING TRAVELING-WAVE ANTENNA RELAYS FOR HIGH-SPEED VEHICULAR COMMUNICATIONS |
摘要 |
<p>An antenna relay system for facilitating wireless communication between mobile terminals on a high-speed rail vehicle and stationary base stations with substantially reduced Doppler shift effects comprises matched traveling wave directional antennas mounted to a high-speed rail vehicle and positioned collinearly alongside the railway. Both antennas continually transmit and receive at a fixed angle relative to the motion of the train so as to circumvent the Doppler shift. The signal transmitted or received by the stationary antenna is conducted to a nearest node for communication with an access network.</p> |
