DIGITAL COUPLER FOR CONTROL AND TRANSMISSION BOARD IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A digital coupler for control and transmission board which capable of minimizing an area of a chip and improving an operation speed by directly coupling input data without dividing sectors thereof and dividing and outputting sectors thereof is provided. CONSTITUTION: The digital coupler which controls and transmits a base station in a mobile communication system comprising: a latch(200) for receiving and latching each channel of elements boards and outputting a signal having a CRC bit; an adder(210) for receiving the output of the latch(200), adding it to a channel signal, and outputting the result signal in sectors; and a demultiplexor(215) for receiving the output of the adder(210) in sectors and transmitting it in channels.
