TDM INTERCELL CONNECTION FIBEROPTIC BUS LINK FOR PERSONAL RADIO-COMMUNICATION SYSTEMS

To connect among many radio base stations by using optical fiber bus l ink in microcellular system, subcarrier multiplexing (SCM) is excellen t in simplicity and flexibility. But performance degradation due to op tical beat noises is severe problem. To solve this problems, this pape r proposes a new type of intercell connection bus fiber-optic link (IC BL) using time division multiplexing, called TDM-ICBL. This paper also analyzes transmission performance of TDM-ICBL theoretically and compa res with SCM-ICBL. The analysis clarifies that while the number of RBS s connected to SCM-ICBL is severely restricted by beat noises, TDM-ICB L is more useful than SCM-ICBL when there are many number of connected RBSs.
