METHOD AND APPARATUS FOR COMBINING INTERLEAVER AND TONE-MAPPER IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed are a method and a device for efficiently combining an interleaver and a tone mapper in a wireless communications system. The method for combining an interleaver and a tone mapper using a memory structure according to an embodiment of the present invention comprises the steps of: identifying a low density parity check (LDPC) code or a binary convolution coding (BCC) code; storing at least one log likelihood ratio (LLR) in a plurality of addresses of a plurality of fragment memories included in a transceiver, wherein the fragment memories support tone mapping for the LDPC code and interleaving for the BCC code; and reading the fragment memories based on the result of the identification.
