PHYSICAL LAYER PROCESSING APPARATUS FOR WIRELESS COMMUNICATION SYSTEM USING CDMA

摘要

PURPOSE: A physical layer processing apparatus for a wireless communication system using CDMA(Code Division Multiple Access) is provided to process data in a physical layer of the communication system. CONSTITUTION: The address mapping of bits in a physical channel buffer(84) is determined from the address of bits in the first interleaver buffer(82). Addresses of the physical channel buffer(84) are determined in response to the addresses of the bits after rate matching, bit scrambling, the second interleaving and physical channel mapping. The bits are directly read from the first interleaver buffer(82) and are written to the physical channel buffer(84) using the determined addresses of the physical channel buffer(84).
