RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD IN MULTI-CARRIER COMMUNICATION |
摘要 |
<p>There is provided a radio transmission device capable of improving the system throughput in multi-carrier communication. The device includes IQ separation units (20-1 to 20-K) for separating an I channel and a Q channel from the inputted symbol and inputting them into control units (22). The control units (22-1 to 22-K) reduce the power of the parity bit by reducing the amplitude of the channel corresponding to the parity bit among the I channel and Q channel inputted. IQ multiplexing units (24-1 to 24-K) multiplex the I channel and Q channel inputted from the control units (22-1 to 22-K) and return them to a symbol, which is inputted to an IFFT unit (26). The IFFT unit (26) subjects the symbol inputted from the IQ multiplexing units (24-1 to 24-K) to inverse fast Fourier transform (IFFT) and maps it to respective sub-carriers f<sub</p> |
