    Abstract: An apparatus and method for transmitting/receiving data in a mobile communication system using multiple antennas are provided. A receiver estimates a fading channel of received data, selects a weight set relative to a maximum data transmission rate from at least one weight set with elements of a plurality of orthogonal weight vectors, and transmits feedback information including the selected weight set and channel-by-channel state information to a transmitter. The transmitter demultiplexes data to be transmitted on a basis of the feedback information into at least one sub-data stream, multiplies each sub-data stream by an associated weight, and transmits the data.

    Abstract: A method and an apparatus are provided for decoding a channel in a communication system using a LDPC code. A shortening pattern and a puncturing pattern are determined based on a received signal. A value of a shortened bit is set to 0 according to the determined shortening pattern, erasures are set according to the determined puncturing pattern, and LDPC decoding is performed, when bits exist which have been used to perform shortening or puncturing. Determining the shortening pattern and the puncturing pattern includes setting a predetermined ratio of the number of punctured bits to the number of shortened bits.
