Abstract :
This paper presents the results of a series of evaluation trials undertaken in the scope of the ACTS project AWACS in order to investigate the feasibility of the use of directional antennas to support high bit rate transmissions using a single carrier unequalised modem. The relationship between the antenna directivity, propagation statistics and modem performance are reported here. The results illustrate the effectiveness of correctly aligned, high gain antennas in reducing the undesired effects of multipath propagation. Further, the transceiver trials indicate the need for balancing antenna directivity at both ends of the link
