A design of synchronization method for TDOA-based positioning system

This paper proposes the synchronization method for TDOA-based Localization system. It is verified by using the commercial SDR-based receiver. Synchronization between the channels is required to obtain the TDOA measurement in multi-channel environment. It is classified into the data, phase and clock synchronization and the arbitrary signal is generated to synchronize the data and phase. The generated signal is made up of the gold code for data synchronization and the continuous wave of 4kHz for phase synchronization.
