| Abstract(in English) | In order to realize high-speed wireless communications, higher frequency and broader band are being advanced. However amplitude and phase errors occur between the I and Q signal components in the quadrature modulator / demodulator. As a method of blind compensation scheme for IQ imbalance, a method using a constant norm algorithm (CNA) has been proposed. But we confirmed the pattern in which the BER characteristics worsen than before compensation. In this paper, we examined the introduction of decision feedback type equalizer and confirmed its effectiveness from BER characteristics. |
