TDMA frame synchronization of mobile stations using a radio clock signal for short range communications
Wei Zhu · 2002
A frame/slot synchronization protocol called ESDA (external synchronization with decentral adjustment) to support real time oriented TDMA channel switched medium access for short range mobile radio networks (SR-MRN) is described. This protocol is based on an external time signal of the radio clock DCF77 to establish a global synchronization, and a decentralized synchronization algorithm to adjust the synchronization time point to achieve the required precision. Experimental and simulative results show that this method can achieve the required precision, and is suitable for commercial application because of its cheapness. It is superior to totally decentralized methods.>
