Autonomous inter base station synchronisation via a common broadcast control channel

摘要: Studies a mutual synchronisation technique between base stations (BSs) which operates over the air. First, different possible structures for broadcast control channels (BCCHs) are presented with their main functionalities. A structure of common BCCH group BSs sharing same carrier time multiplexing is proposed. This may be used to provide synchronisation. Existing algorithms then reviewed. For such algorithms, each BS combines measurements (estimated offset) from neighbouring determine its own phase. Computer simulations based on TDMA system evaluate stability and convergence speed algorithm. >
