PROBLEM TO BE SOLVED: To provide an orthogonal frequency division multiplex (OFDM) system operating at a one-GHz or less frequency band.SOLUTION: Physical layer logic implements a new preamble structure having a new signal field. On the basis of the new preamble structure, the preamble structure and/or a preamble is stored in a medium available for machine access. Generation and transmission of communication with the new preamble structure is performed. Reception and detection of communication with the new preamble is performed. |
