Multicarrier transmission method, multicarrier modulation signal transmission apparatus, multicarrier modulation signal reception apparatus, multicarrier modulation signal transmission method, and pilot signal generation method
Multicarrier transmission method, multicarrier modulation signal transmission apparatus, multicarrier modulation signal reception apparatus, multicarrier modulation signal transmission method, and pilot signal generation method
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 {α, α, −α, −α}, {α, −α, −α, α}, {−α, α, α, −α}, and {−α, −α, α, α} where α 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.
