| Abstract | This study presents an investigation into the link performance of a TDMA sectorized
cellular system employing perfect power control, frequency hopping and discontinuous
transmission. Two criteria of link performance are presented: signal-to-interference ratio
considerations and traffic considerations. For signal-to-interference ratio computations for both
up-link and down-link cases with various cluster sizes with different sectorization schemes are
considered where the transmission is subjected to an inverse fourth power path loss law and lognormal shadowing. For traffic capacity and spectrum efficiency computations we considered a
TDMA system using GSM specifications.
It is found that sectorization improves signal-to-interference ratio for all practical cluster
sizes, and, if different cluster sizes are considered, sectorization provides higher traffic capacity
and higher spectrum efficiency than that of without sectorization case. Six sector system performs
better than three sector and without sectorization configurations. |
