摘要： The present invention relates to an orthogonal frequency division multiplexing wireless local area network (LAN) transmitting/receiving system for providing expanded service coverage, and a method thereof. A first OFDM modulation is performed for an even-numbered time, and a second OFDM modulation is performed for an odd-numbered time. A transmitting frame including a plurality of signal fields according to the first and second OFDM modulation is transmitted. The receiving system determines whether a signal field is repeatedly generated in the frame. If the signal field is not repeatedly generated, corresponding demodulation is performed. If repeatedly performed, the signal field is demodulated by using first bit allocation information and second bit allocation information having a ½ value of the first bit allocation information. A data field is demodulated according to the demodulated signal field.

摘要： The present invention relates to a transmitting apparatus of a wireless communication system, and a method thereof. The transmitting apparatus monitors receiving of response data for data that has been transmitted to a receiving end, and sets a first parameter for counting successful receipts according to receiving on the response data. The transmitting apparatus demodulates the response data and extracts the number of demodulated data that satisfies a first set value. Subsequently, it is determined whether the first parameter satisfies a second set value and the number of demodulated data satisfies a predetermined ratio of a referential amount of packets. According to the present invention, an efficient transmission mode for a channel state can be provided with reference to an extracted number of soft-decision data from response data received at a receiving end. In addition, a transmission mode can be determined by using only response data according to the present invention.

摘要： The present invention relates to an orthogonal frequency division multiplexing wireless local area network (LAN) transmitting/receiving system for providing expanded service coverage, and a method thereof. According to the present invention, first OFDM modulation is performed for an even-numbered time, and second OFDM modulation is performed by changing subcarrier allocation positions of first OFDM modulated symbols for an odd-numbered time. In addition, a transmitting frame including a plurality of signal fields according to the first and second OFDM modulation is transmitted. The receiving system determines a format configuration of the received frame to determine whether a signal field is repeatedly generated in the frame. When it is determined that the signal field is not repeatedly generated, corresponding demodulation is performed. When it is determined that the signal field is repeatedly performed, the signal field is demodulated by using first bit allocation information and is demodulated by using second bit allocation information having a 1/2 value of the first bit allocation information. A data field is demodulated according to the demodulated signal field.
