TRANSMITTING DEVICE, RECEIVING DEVICE, TRANSMITTING AND RECEIVING METHOD FOR WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A transmitting device, a receiving device, and a transceiving method of a wireless telecommunications system are provided to increase data transmission capacity by carrying out a modulation operation through a 64-quadrature pulse height modulating method. CONSTITUTION: A plurality of transmission units(130a,130b,130c) respectively copes with a plurality of sub-bands. A splitter(120) selects at least one of the same transmission units according to the data transfer rate. The splitter transfers an input signal to the selected transmission unit. Each transmission unit changes an output signal received from the splitter. A scrambler(110) outputs the input signal by scrambling the source data. Each of the transmission units comprises an encoder(131) which performs channel coding in regard to the output signal from the splitter, a modulator(133) which modulates the output signal from the encoder, a reverse Fourier transformer(135) which transforms the output signal from the encoder from a frequency area into a time area.
