A wireless communication apparatus and a wireless communication method having higher efficiency and reliability than conventional arts when performing communication by OFDMA employing a coding scheme are provided. A communication apparatus is provided with a processing unit for performing symbol processing on a communication frame, a detection unit for detecting a value indicating a changing state of a propagation path, a change processing unit for controlling the processing unit to change a unprocessed symbol, which is generated when the symbol processing is performed on each combination of a predetermined number of symbols in a direction of a time axis, to a control symbol based on the value indicating the changing state, or to perform the symbol processing on the unprocessed symbol in a direction of a frequency axis, and a transmission unit for transmitting a communication frame after control.
