Abstract: 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.

Abstract: PURPOSE: A preamble transmission method for estimating multiple channels, a reception method, and a device thereof are provided to effectively estimate a channel by receiving a signal through a relay terminal or an antenna in an environment in which a plurality of paths is existed. CONSTITUTION: A terminal (100) comprises a processor (110), a memory (120), and a radio frequency (RF) unit (130). The processor transmits a channel estimation sequence when the terminal is operated as a relay terminal. The terminal estimates channels by restoring the channel estimation sequence in the process when the terminal is operated as a purpose terminal. The memory stores diverse information for operating the processor by connecting to the processor. The RF unit receives or transmits the wireless signal by connecting to the processor.
