TRANSMITTING DEVICE, RECEIVING DEVICE, 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 1 that generates data symbols; a fixed-symbol arrangement unit 2 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 3 that converts the block symbol to a frequency domain signal that includes N samples; an interpolation processing unit 6 that performs interpolation processing on the frequency domain signal; and a CP insertion unit 7 that generates the block signal by inserting a Cyclic Prefix into a signal that has undergone the interpolation processing.
