ABSTRACT:
An apparatus and a method for synchronization in a channel card in a mobile communication system are provided. A channel card for synchronizing a Digital Signal Processing (DSP) modem and a system clock in a mobile communication system includes the DSP modem for sending a reference signal, informing of a start of a transmission, to a Field-Programmable Gate Array (FPGA) modem, and the FPGA modem for comparing a reception time of the reference signal with a Global Positioning System (GPS) timer, for recording a GPS timer value corresponding to a start point based on the comparison, and for sending to the DSP modem the recorded GPS timer value corresponding to the start point at a preset GPS timer reference time.
