摘要
A tile index generation apparatus for allocating subchannels of a control channel and a diversity channel, a subchannel allocation apparatus for allocating subchannels of a diversity channel, and a subchannel allocation apparatus for allocating subchannels of an adaptive modulation coding (AMC) channel, which are used for an uplink of an orthogonal frequency division multiplexing access (OFDMA) system, are provided. With these subchannel allocation apparatuses, optimum designs for the uplink subchannel allocation in the OFDM scheme can be provided to a modulator of a subscriber station and a demodulator of a base station, and so the uplink subchannel allocation apparatus has a simple structure and an enhanced transmission speed.
