TRANSMISSION APPARATUS, RECEPTION APPARATUS, AND COMMUNICATION SYSTEM

摘要

A transmission apparatus that transmits a block signal that includes a plurality of data symbols, includes: a symbol generation unit that generates data symbols; a fixed-symbol arrangement unit that generates a block symbol by arranging data symbols and fixed symbols such that the fixed symbols are inserted at predetermined positions in a block signal; a time-frequency conversion unit that converts the block symbol to a frequency domain signal that includes N samples; an interpolation processing unit that performs interpolation processing on the frequency domain signal; and a CP insertion unit that generates the block signal by inserting a Cyclic Prefix into a signal that has undergone the interpolation processing.

1. A transmission apparatus that transmits a block signal that includes N (N is an integer of one or larger) data symbols, the transmission apparatus comprising:
a data-symbol generation unit that generates a data symbol; a symbol arrangement unit that generates a block symbol by arranging the data symbol and F (F is an integer of two or larger) same-quadrant symbols, which become signal points in a same quadrant in a complex plane, such that the same-quadrant symbols are inserted at predetermined positions in a block signal; a time-frequency conversion unit that converts the block symbol to a frequency domain signal that includes N samples; an interpolation processing unit that performs interpolation processing on the frequency domain signal; and a CP insertion unit that generates the block signal by inserting a Cyclic Prefix into a signal that has undergone the interpolation processing.
