Patent ID: 7061988

Claim:
An interleaver memory access apparatus of a mobile communication system comprising: an interleaver memory; a code symbol repetition unit for processing sequentially inputted code symbols according to a transfer rate and writing the code symbols by 1-column in the interleaver memory; a shift register unit for receiving the code symbols read by 1-row from the interleaver memory and storing them in a certain unit; and an address generation/control logic for controlling operations of the interleaver memory and the shift register unit, wherein the code symbol repetition unit comprises: code symbol input unit for inputting code symbols according to an input control signal of the address generation/control logic; first and second switching units for switching the code symbols outputted from the code symbol in put unit according to first and second switching signals of the address generation/control logic; first and second register units for storing code symbols outputted from the first and second switching units; and a code symbol output unit for stimultaneously outputting code symbols stored in the first and second register units, to the interleaver memory according to a transmission signal of the address generation/control logic.
