Abstract:
1. A repetition apparatus for repeatedly transmitting a data packet, comprising: a dual data generator for generating an original information bit sequence to be transmitted, and generating a duplicated information bit sequence identical to the original information bit sequence; a channel encoder for respectively dividing each of the original information bit sequence and the duplicated information bit sequence into a plurality of information bits, and generating an original coded data packet for the original information bit sequence from the plurality of information bits, and generating a duplicated coded data packet for the duplicated information bit sequence from the plurality of information bits; and a transmitter for sequentially transmitting the original coded data packet and the duplicated coded data packet, wherein the original coded data packet and the duplicated coded data packet corresponding to the original coded data packet respectively include a corresponding information bit at a same location in the respective sequences, and alternately include each of a plurality of parity bits associated with the corresponding information bit according to different puncturing patterns for each of information bits for the original information bit sequence.
