Abstract:
1. A transmitting apparatus, comprising: a training signal generating unit operable to generate a training signal; a transmission data generating unit operable to generate data desired to be transmitted; a quadrature modulation unit operable to subject a data signal based on the data desired to be transmitted and the training signal to quadrature modulation to form a quadrature modulated signal; a first transmitting unit operable to transmit a first signal component of the quadrature modulated signal as a signal in which data desired to be transmitted is modulated; and a second transmitting unit operable to transmit a second signal component of the quadrature modulated signal as the training signal, the second signal component being orthogonal to the first signal component, the first signal component being an in-phase signal component, and the second signal component being a quadrature signal component.
