Abstract:
A transmission apparatus includes: a data-symbol generation unit that generates data symbols for one block in each block; a storage and processing unit that stores therein a data symbol at a first position, among the data symbols for one block, as a copied symbol; a symbol insertion unit that generates a block symbol by putting the data symbols and the copied symbol such that the copied symbol stored in the storage and processing unit are inserted at a second position of the data symbols for one block; a time/frequency conversion unit that converts the block signal into a frequency domain signal; an interpolation unit that performs interpolation processing on the frequency domain symbol; and a CP insertion unit that generates the block signal by inserting a Cyclic Prefix into a signal on which the interpolation processing has been performed.

Claim (Index 10):
A reception apparatus that receives a signal transmitted from the transmission apparatus according to  claim 1  as a received signal, the reception apparatus comprising:\n a CP removal unit to remove a Cyclic Prefix from the received signal; \n a DFT processing unit to generate a frequency domain signal by performing DFT processing on the received signal from which the Cyclic Prefix has been removed; \n a channel estimation unit to perform estimation of a channel on the basis of the frequency domain signal; \n an equalization unit to perform equalization processing on the basis of the frequency domain signal and an estimation result of the channel; \n an undersampling unit to perform on a signal on which the equalization processing has been performed; \n a pilot signal removing unit to remove a pilot signal from a signal on which the undersampling has been performed; \n an IDFT processing unit to perform IDFT processing on a signal from which the pilot symbol has been removed; \n a symbol selection unit to select a data symbol at a first position from a signal on which the IDFT processing has been performed; \n a storage unit to store therein a selected symbol selected by the symbol selection unit; and \n a demodulation unit to\n demodulate a data symbol other than a data symbol at a second position from the signal on which the IDFT processing has been performed, and \n demodulate the data symbol at the second position by using the data symbol at the second position and the selected symbol stored in the storage unit.
