APPARATUS FOR TRANSMITTING AND RECEIVING DIGITAL MULTIMEDIA BROADCASTING AND METHOD THEREOF
摘要
PURPOSE: A DMB(Digital Multimedia Broadcasting) transceiving apparatus and method are provided to include specific information in a pilot signal for channel estimation, thereby improving a data transfer rate. CONSTITUTION: A pilot signal generator(120) is used for estimation of a transmission channel in a receiving unit. The pilot signal generator creates a pilot signal. The pilot signal comprises one or more information. A subcarrier mapping unit(130) maps the pilot signal to subcarrier corresponding to the pilot signal. A modulator(140) modulates the output of the subcarrier mapping unit. The pilot signal has a value about the specific information, not a value which the receiving unit has previously acknowledged.
