Claim:
1. A transmission apparatus that transmits a block signal including a plurality of data symbols, the transmission apparatus comprising: a data-symbol generator circuit that generates data symbols; a symbol arranger circuit that arranges the data symbols and same-quadrant symbols in a time domain such that two or more same-quadrant symbols that become signal points in a same quadrant in a complex plane are inserted at predetermined positions in a block signal to generate a block symbol; an interpolator circuit that performs interpolation processing on the block symbol; and a Cyclic Prefix (CP) inserter circuit that inserts a Cyclic Prefix into a signal on which the interpolation processing has been performed to generate the block signal, wherein the symbol arranger circuit arranges the same-quadrant symbols at a head of a symbol to be copied as a Cyclic Prefix and a head of the block symbol, and wherein the interpolator circuit performs the interpolation processing such that an interpolated point that has interpolated between a last symbol of the block symbol and a head symbol of the block symbol is added behind the last symbol.
