| Summary: | 碩士 === 國立中正大學 === 電機工程學系 === 84 === ABSTRACT System capacity improvement is the main drive behind
the development ofthe new time division multiple access (TDMA)
digital cellular system. Manycellular standards are developed,
such as GSM, DECT, etc... This thesis isconcerned with initial
access procedure and handoff procedure of PersonalAccess
Communication System (PACS). In this thesis, we set up two
different TDMA cellular frequency reusesystems based on
PACS system by using BONeS (Block Oriented
NetworkSimulator) simulation tool. Based on these
simulation systems, weindividually investigate initial
access procedure and handoff procedure inPACS system, and find
out the optimal values of parameters. Finally, wepropose a
new criterion to update ALT/TST trigger procedure to improve
thesystem performance.
