METHOD FOR COMMUNICATION, AND TRANSMITTER AND RECEIVER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To allow a transmitting speed and a transmitting quality of data to be compatible. SOLUTION: A serial-to-parallel converter 202 converts a transmitting digital signal 201 of a channel A into parallel data of a disposition according to a frame constituting signal 222. A reverse discrete Fourier transforming unit 204 reverse discrete Fourier transforms a parallel signal 203 of the channel A. A radio unit 206 converts a signal 205 into a radio frequency. A power amplifier 208 amplifies a power of a transmitting signal 207. A serial-to-parallel converter 212 converts a transmitting digital signal 211 of a channel B into parallel data of a disposition according to the frame constituting signal 222. A reverse discrete Fourier converter 214 reverse discrete Fourier converts a parallel signal 213. A radio unit 216 converts a signal 215 after the conversion into a radio frequency. A power amplifier 218 amplifies a power of a transmitting signal 217. COPYRIGHT: (C)2004,JPO
