FREQUENCY DIVISION MULTIPLEX TRANSMISSION AND RECEPTION APPARATUS AND WAVENUMBER DIVISION MULTIPLEX TRANSMISSION AND RECEPTION APPARATUS, AND METHOD THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide a technology of reducing multipath interference (MPI) without the need for using a multipath canceller. PSOLUTION: In a frequency division multiplex transmission method for transmitting data by symbols and frequency spectrums unique to a mobile station, transmission data are coded, the coded data are modulated, a time region of each symbol in a transmission symbol sequence resulting from modulated data is compressed, the symbol is repeated for a prescribed number of times, each symbol of the obtained repeated symbol sequence is rearranged to be the arrangement of the transmission symbol sequence to generate a phase changed at a speed unique to the symbol, rotation of a phase unique to the symbol is applied to each symbol of the repeated symbol sequence after the rearrangement to generate a phase changed at a speed unique to the mobile station, phase rotation unique to the mobile station is applied to the symbol sequence subjected to the phase rotation, and the symbol sequence subjected to the phase rotation is transmitted.
