Abstract
A radio communication method according to an embodiment is a radio communication method for transmitting a signal from a transmitter to a receiver using a single carrier, in which the transmitter generates two or more training signals using a symmetric subcarrier at the time of training to perform an OFDM modulation, and shapes a spectrum of each of the OFDM-modulated training signals to be close to a single carrier spectrum, and in which the receiver adjusts the timing of two or more training signals, using a single carrier time domain correlation sequence at the time of training, estimates a channel response and an IQ imbalance from the two or more training signals whose timing is adjusted, compensates for the estimated IQ imbalance, and demodulates the compensated signal.
