Abstract: An apparatus and a method for synchronizing a system of a base station modem based on a DSP(Digital Signal Processor) are provided to facilitate time synchronization of the system between base stations by performing synchronization and controlling a point of time of a transmitting signal by measuring a difference value between reference clocks for synchronization and the DSP. An apparatus for synchronizing a system of a base station modem based on a DSP comprises a DSP chip(200) and an external device(202). The DSP chip is mounted on the base station modem. When a control signal for synchronizing the system is received in the DSP chip, predetermined numbers of digital transmitting signal samples are made and transmitted, and a point of transmitting time is adjusted according to a control signal for adjusting the point of transmitting time of the transmitting signal. The external device transmits the control signal for synchronizing the system to the DSP chip and receives the digital transmitting signal samples. The signal sample is compared with a synchronization clock signal received from a base station controller, and a time distance between two signals is calculated. The external device transmits the control signal for adjusting the point of transmitting time of the transmitting signal of the DSP chip for matching the time distance between two signals so as to match a reference point of transmitting time of the transmitting signal of the DSP chip and a point of time of the synchronization clock signal.
