CHANNEL DATA MULTIPLEXING APPARATUS AND METHOD FOR SUPPORTING VARIABLE TRANSMISSION RATE

摘要

Provided is a channel data multiplexing apparatus and method for supporting a variable transmission rate. The channel data multiplexing apparatus includes an input memory for receiving multi-channel baseband data in parallel and storing the baseband data at a first clock rate; an output memory for reading the baseband data stored in the input memory at a second clock rate and storing the baseband data; a multiplexing unit for reading the baseband data stored in the output memory in channel sequence at a third clock rate and outputting the baseband data in serial; and a control unit for controlling address processing and clock rates for data read/write (storage) from/in the input and the output memories and the multiplexing unit depending on a transmission mode.
