SYMBOL BUFFER MEMORY UNIT IN A BASE STATION MODEM OF A MOBILE COMMUNICATION SYSTEM AND A METHOD THEREFOR, CONCERNED WITH SIMPLIFYING A STRUCTURE OF A CONTROL LOGIC AND A TABLE MULTIPLEXER

摘要

PURPOSE: A symbol buffer memory unit in a base station modem of a mobile communication system and a method therefor are provided to reduce an overall size of hardware by simplifying a structure of a control logic and a table multiplexer. CONSTITUTION: A buffer memory(230) sequentially stores symbol data among logical channels according to an input order. A start address table(200) stores address information of the buffer memory(230) where the first data symbol of each logical channel, among the symbols stored in the buffer memory(230), is positioned corresponding to each logical channel. A multiplexer(220) selectively outputs physical address information of the first symbol data of each logical channel stored in the start address table(200) by a table of a channel selector(210) storing enable signals set for each logical channel.
