RADIO COMMUNICATION DEVICE AND RADIO COMMUNICATION METHOD

摘要

Provided are a radio communication device and a radio communication method which have a higher efficiency and reliability as compared to the conventional device and method when performing an OFDMA communication by using the encoding method. The communication device (100) includes: a processing unit (160) which performs a symbol process in a communication frame; a detection unit (120) which detects a value indicating a variation state of a propagation path; a modification processing unit (170) which controls the processing unit (160) when performing a symbol process for each predetermined number of symbol sets in the time axis direction; and a transmission unit (110) which transmits a communication frame after the control. The modification processing unit (170) controls the processing unit (160) to modify an unprocessed symbol to a control symbol in accordance with a value indicating the variation state or to perform the symbol process on the unprocessed symbol in the frequency axis direction.
