Abstract
A data-transmission-side communication apparatus includes a mapping unit that executes a mapping for a data sub-carrier based on a multipath delay time in a transmission path and a guard-band adding unit that changes an amount of a guard band to be added to a signal on the data sub-carrier depending on information on the guard band obtained based on the multipath delay time. A data-reception-side communication apparatus includes an equalizing unit that suppresses a multipath exceeding a guard interval based on the information on the guard band and a demapping unit that executes a demapping for an equalized signal based on the multipath delay time.
