摘要:
An apparatus and a method for channel encoding using a Low-Density Parity-Check (LDPC) code, the method comprising: determining a number of parity bits for puncturing; determining a number of parity bit sets based on the number of parity bits for puncturing, each of the parity bit sets being formed by parity bits at a predetermined interval; and puncturing parity bits based on the number of parity bit sets and a predetermined order of parity bit sets to be punctured, wherein the predetermined order of parity bit sets is determined as 27, 13, 29, 32, 5, 0, 11, 21, 33, 20, 25, 28, 18, 35, 8, 3, 9, 31, 22, 24, 7, 14, 17, 4, 2, 26, 16, 34,19,10,12,23,1,6,30,15.
摘要:
A method and apparatus for transmitting control information in a communication system is provided. The number of LDPC blocks, through which L1 post-signaling information is to be transmitted, is determined according to the total number of bits of the L1 post-signaling information. The number of input information bits of each LDPC block is calculated when the determined number of LDPC blocks is plural. The number of puncturing bits among parity bits of each LDPC block is determined considering a modulation order. A frame including one or multiple LDPC blocks generated through the preceding steps is transmitted.

A method and apparatus for reducing a Peak to Average Power Ratio (PAPR) in a digital broadcasting system are provided. Reserved tones are determined, and used to transmit a signal having an impulse characteristic that does not collide with a pilot signal of a preamble in a frame.
摘要:
A method and apparatus for transmitting/receiving control information in a wireless communication system are provided, in which physical layer signaling information to be transmitted in a frame is determined, a coded block is generated from signaling information having a fixed number of bits included in the physical layer signaling information, and a frame including the coded block is transmitted. The signaling information having the fixed number of bits includes information required for receiving other signaling information having a variable number ofbits.
