Abstract: An adaptive transmission apparatus according to a channel state in an OFDMA(Orthogonal Frequency Division Multiplexing Access) system and a method thereof are provided to secure a transmission quantity by setting a CP(Cyclic Prefix) length using a CP value based on an initial frame having a same length with a guard interval length and transmitting a frame. An IFFT(Inverse Fast Fourier Transform)(302) performs an IFFT process for modulated data. A conversion unit(304) converts parallel data into serial data. A CP insertion unit inserts a CP to prevent interference between symbols according to a multi path fading. A digital/analog converter converts the output data of the CP insertion unit into analog data. A transmission unit(310) transmits the converted analog data. A receiving unit(312) receives and provides the data transmitted from a secondary device to a CP value decoder(314). The CP value decoder decodes the data, extracts the CP value from the encoded data and provides the extracted CP value to a CP control unit(316) and a power control unit(318). The CP control unit compares the CP value with a guard interval length, determines a CP length to be added to a front part of a symbol of a frame to be transmitted, and controls the CP insertion unit. The power control unit cuts off a power a primary device for a difference time between the guard interval length and the CP length determined by the CP control unit.
