摘要： PROBLEM TO BE SOLVED: To surely and accurately measure a round trip time (RTT) between a transmitter station and a receiver station. SOLUTION: When a MAC superframe enters a contention interval, an RTT measuring section 604 transmits an RTT test command (RTT_TEST.CMD 114) to a receiver station 611 and starts measuring the RTT by starting a timer circuit of the RTT measuring section 604. In response to the RTT test command 114, an RTT response transmitting section 614 performs predetermined processing that requires a processing time 115, and transmits an accepted response command (ACCEPTED.RSP 116) to a transmitter station 601. When the ACCEPTED. RSP 116 is received, the RTT measuring section 604 stops the timer circuit and transmits, to a DTCP command transmitting/receiving section 602, a command of an RTT measurement completion report 117 including a timer value measured using the relevant timer circuit.

摘要： PROBLEM TO BE SOLVED: To provide a method for transmitting an orthogonal frequency division multiplex signal that can accurately correct a change in received level and/or in frequency band, and consequently produce no erroneous determination on demodulated data, and to provide a receiving apparatus therefor.
SOLUTION: In an orthogonal frequency division multiplex signal that is transmitted from a transmitting side to a receiving side, in addition to a symbol Sm that contains data to be transmitted, specific symbols S0 that have a predetermined specific pattern are intermittently included. On the receiving side, based on the received specific symbol S0, a change in received level and/or a change in frequency band of the received signal are detected and corrected. Because the specific symbol S0 has the specific pattern, a change in the level and/or a change in the frequency are strongly correlated with the change in the received level and/or the change in the frequency band of the received signal. Accordingly, it is possible to exactly detect the change in the received level and/or in the frequency band of the received signal, and consequently a highly accurate correction can be carried out.
