The objective of the present invention is to create a soft estimation value that avoids the loss of bit information, and to implement a turbo equalization process, in a wireless transmission device and a wireless transmission system wherein a terminal process is not performed in an error correction encoding unit, and an inter-frame interleave process is used. This wireless transmission system has a transmitting device and a receiving device, and is characterized in that the transmitting device is equipped with an error correction encoding means, a first interleaving means, a second interleaving means, and a digital modulation means, and the receiving device is equipped with a means for detecting a received signal, a demapping means, a second deinterleaving means, a means for storing a received bit logarithmic likelihood ratio in a frame buffer, a frequency interleaver data extraction unit that extracts data of a prescribed period, a decoding unit, and a hard determination unit. |
