| 摘要 |
In a transmitter, at least one pilot carrier which is modulated with a signal sequence including a reference pilot signal sequence represented by any of amplitude modulation vectors {±, ±, -±, -±}, {±, -±, -±, ±}, {-±, ±, ±, -±}, and {-±, -±, ±, ±} where ± represents a real number other than 0, is generated, and an OFDM/OQAM multicarrier modulation signal is transmitted. In a receiver, the OFDM/OQAM multicarrier modulation signal is demodulated, and transmission channel characteristics are estimated and corrected based on two successive demodulation vectors in a time direction which are obtained by demodulating the pilot carrier.
