Abstract:
1. A receive method in a communication system, comprising the steps of: receiving a signal of a carrier band; generating an in-phase signal and a quadrature signal from the signal received in the receiving step; compensating an orthogonality error and gain imbalance for said in-phase signal and said quadrature signal; and inputting said in-phase signal and said quadrature signal into a first complex frequency converter, and also inputting said in-phase signal and said quadrature signal into a second complex frequency converter, wherein the first complex frequency converter complex-multiplies said in-phase signal and said quadrature signal by a first analytic sine wave having a first frequency to generate a first complex frequency band signal, and the second complex frequency converter complex-multiplies said in-phase signal and said quadrature signal by a second analytic sine wave having a second frequency to generate a second complex frequency band signal.
