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： A Signal-to-interference ratio (SIR) measuring apparatus in a multiple antenna high data rate packet transmission system measures signal energy to interference energy ratio by using pilot signals that are orthogonal to each other between antennas signals and used by a receiver for separating the signals transmitted from all of the transmitting antennas from each other. The SIR measuring apparatus comprises a signal energy measuring unit, an interference energy measuring unit and a SIR measuring unit. The signal energy measuring unit measures signal energy by synthesizing after coherently integrating and non-coherently integrating values that are obtained by correlating a received signal with pilot patterns equal to the pilot patterns of transmitted antenna signals, respectively. The interference energy measuring unit measures interference energy by coherently integrating and non-coherently integrating after correlating the received signal with another pattern that is orthogonal to the pilot patterns of the transmitted antenna signals but is not transmitted. The SIR measuring unit measures SIR by using the measured signal energy and the measured interference energy.

摘要： The present invention relates to a method for detecting a signal in an MIMO system. In the method, a received signal is detected in a zero forcing (ZF) method, and a first detection interval is established from the signal detected in the ZF method. The received signal is detected within the first detection interval in a maximum likelihood (ML) method, a second detection interval is established from the signals respectively detected in the ZF method and the ML method. A final solution is determined by detecting the received signal within the second detection interval in the ML method.
