摘要： The disclosed invention determines whether a reception packet is an MM packet or a GF packet with precision and avoids unnecessary decoding operations performed at the GF-packet-reception time and inefficient communications.An OFDM symbol including 52 tones is transmitted when the MM packet is used, but an OFDM symbol including 56 tones is transmitted when the GF packet is used. Therefore, it is verified whether or not a signal exists in an FFT output at each of ±27 and 28 shown in a subcarrier index so that the format of the reception packet is determined. Otherwise, the packet format is determined on the basis of the Cyclic-Shift amount that changes for every format. When the GF packet is used, decoding processing performed in an L-SIG and afterward is stopped.
摘要翻译：所公开的发明精确地确定接收分组是MM分组还是GF分组，并且避免在GF分组接收时间和低效通信中执行的不必要的解码操作。当使用MM分组时，发送包括52个音调的OFDM符号，但是当使用GF分组时，发送包括56个音调的OFDM符号。因此，验证在子载波索引中示出的每个±27和28处的FFT输出中是否存在信号，从而确定接收分组的格式。否则，根据每种格式的循环移位量来确定分组格式。当使用GF分组时，停止在L-SIG中执行的解码处理。

摘要： A radio-communication device performs processing in a communication environment in which an OFDM (Orthogonal Frequency Division Multiplexing) modulation method is used. The radio-communication device includes a signal-reception unit that receives a MIMO (Multi Input Multi Output) signal, a data-decoding unit that decodes the MIMO signal, and a data-processing unit that processes data decoded by the data-decoding unit. The radio-communication device also includes a format-determination unit that determines, based on a relative phase difference between a previous packet field and a subsequent packet field adjacent to the previous packet field, a packet format of the MIMO signal. Further, the radio-communication device includes a control unit that stops an operation of the data-decoding unit when the data-processing unit does not support the packet format, which is determined by the format-determination unit. The operation is performed in a field that comes after a field at which the format-determination unit determines the packet format.
