In this work, we provide a new throughput-based antenna selection criterion that considers the entire system design rather than only the channel state information. The performance evaluation was carried out in a measurement campaign in a common outdoor urban scenario. We present our results in terms of physical layer throughput over transmit power. In addition to diversity gains, we also see gains...
In the design of hybrid diversity, two options are possible giving different performances to the diversity system. Both options are analysed in the case of radio links over smooth surfaces. For the calculation of the vertical antenna spacing, some considerations are given in order to generalise a method valid for space diversity.
In line-of-sight radio links over flat terrain or water, a general formula to calculate the antenna separation for space diversity is not appropriate because of the risk of simultaneous fading. A method for determining such a separation is shown and its implementation is described exactly and approximately.
