Antenna selection in a multi-sector packet radio network
C. Lau, Cyril Leung · 2003
The performance of a number of antenna selection schemes in a multisector packet radio network is analyzed. In the model studied, it is assumed that the mobiles are symmetrically distributed within a circle centered at the base station. The circle is divided into M sectors. The station has M directional antennas, each aiming at one sector. Also available at the station are N/sub r/ receivers. Channel access time is divided into slots. At the beginning of a time slot, N/sub r/ antennas are selected and connected to the receivers. Once made, such connections last until the end of the time slot. The optimum scheme is compared with three suboptimum, but easier-to-implement schemes. It is found that for operation in the normal range of channel traffic levels, there is little difference in the throughputs of the four schemes.>
