Abstract:
1. An apparatus for transmitting data in a communication system, the apparatus comprising: a generation unit configured to generate, using a processor, a multi-user data packet including data to be transmitted to a plurality of users, the multi-user data packet including a plurality of medium access control (MAC) protocol data unit (MPDU) subframes, the plurality of MPDU subframes corresponding to the plurality of users; an encoding unit configured to encode, using a processor, the multi-user data packet as a binary convolutional code (BCC) and a low-density parity check (LDPC) code; and a transmission unit configured to transmit the encoded multi-user data packet to the plurality of the users, wherein the encoding unit performs LDPC encoding on the multi-user data packet, and then performs BCC encoding on the LDPC encoded multi-user data packet, and wherein the encoding unit encodes a MPDU subframe in the multi-user data packet, which corresponds to one of the plurality of users, as the LDPC code.
