Title:
APPARATUS AND METHOD FOR TRANSCEIVING DATA
Document Type and Number:
WIPO Patent Application WO/2012/067424
Kind Code:
A2
Abstract:
A data transmitting apparatus generates a plurality of pilot signals to be used in channel estimation in a data receiving apparatus, performs symbol mapping of a plurality of input data signals and a plurality of pilot signals to generate a plurality of data symbols and a plurality of pilot symbols, converts input symbols of a frequency domain including the plurality of data symbols and the plurality of pilot symbols, into real signals of a time domain and performs angle modulation of the real signals. The data transmitting apparatus controls the sizes of sine signals for the angle-modulated real signals by a variable gain in accordance with a control signal, and transmits the real signals.
