Apparatus and method for transmittng and receiving data in communication/broadcasting system

摘要

An apparatus and method for transmitting and receiving data in a wireless communication is provided. The method includes determining a number of zero padding bits, determining a number (Npad) of bit groups in which all bits are padded with zeros, padding the all bits within 0th to (Npad-1)th bit groups indicated by a shortening pattern with zeros, mapping information bits to bit positions which are not padded in Bose Chaudhuri Hocquenghem (BCH) information bits, BCH encoding the BCH information bits to generate Low Density Parity Check (LDPC) information bits, and LDPC encoding the LDPC information bits to generate a zero-padded codeword, wherein the shortening pattern is defined as an order of bit groups defined as 6, 5, 4, 9, 3,2, 1, 8,0,7, 10 and 11. 6545752_1 (GHMatters) P93219.AU.1 MALCOLMP 1/06/2015 [Fig. 4] wU LU U- U o 0 n a CL) 0 cc cc~cc oc 0~0. ccccc -0 CIcCL C: -aDD
