<p>Provided are a turbo equalization device, a turbo equalization method, and a turbo equalization program whereby weight calculation processing can be effectively simplified, and the complexity of iterations can be decreased while retaining characteristics during turbo equalization processing. This turbo equalization device is equipped with an equalization means (10) for executing equalization processing in a frequency region composed of multiple subcarriers. The equalization means (10) includes: filter units (11) for calculating estimated values of transmit signals on multiple subcarriers upon receiving a reception signal and a feedback signal that is generated from a decoded error-correcting code output that is obtained through error-correcting code decoding processing; and a weight calculation unit (12) for calculating weights to be used for calculating the estimated values of the transmit signals. During an iteration of the turbo equalization processing, the weight calculation unit (12) calculates weights only for some subcarriers among the multiple subcarriers, and the filter unit (11) calculates estimated values of the transmit signals on the other subcarriers by using the weights calculated by the weight calculation unit (12).</p> |
