Abstract(in English)	Recently, it has been actively researched the direct conversion scheme for the cost miniaturization and the low power consumption of wireless receivers. IQ Imbalance is one of the problems for the direct conversion receiver, π/2 phase shifter for radio frequency is required in the direct conversion receiver. However, it is difficult to implement the accurate π/2 phase shifter in RF band. Consequently, it varies IQ balance of the demodulated signal. For OFCDM signals, this IQ Imbalance creates the ICI ( Inter-Carrier-Interference ). We propose IQ Imbalance compensation scheme by means of assigning the specific combination of spreading sequence.
