Abstract :
In this paper we have analyzed the performance of adapting beamforming techniques to the Ad-hoc communication between moving vehicles. For the analysis we measured the wireless channel characteristics while moving in high speeds with two vehicles, a transmitter and a receiver. After analyzing the measurement data we found out that the effect of fading can be reduced significantly (9 dB with 99% reliability). Also, the reliable communication range can be increased from not only the beamforming gain but also the gain obtained by reducing the effects of fading. Additionally, in this paper we have analyzed the effects of beamforming to the RMS delay spread using our collected data. Through our analysis we conclude that with beamforming techniques, the adaptive equalizer can be simplified in moving channels.
