Patent attributes
A radio transmission apparatus includes: a guard interval insertion unit that inserts a guard interval in every data block of a transmission data signal; a waveform shaping unit that performs a signal attenuation processing in a time period that includes a boundary of a signal block in which the guard interval has been inserted; and a controller that controls an insertion period of the guard interval by the guard interval insertion unit such that the data block is located in a time period exclusive of the time period which is a signal attenuation period by the waveform shaping unit. By this, in an environment where a signal to which a window function (band limitation) is applied may be received, while the guard intervals are effectively utilized, degradation of reception characteristics due to influence of the band limitation is prevented.
