| 摘要 | A convergence property as ability of removing inter-user interference of turbo equalization is improved in case of using a transmission method in which overlapping of a part of spectrum is allowed among a plurality of users. A wireless control device receiving a signal which is transmitted at the same transmitting timing by a plurality of wireless terminal devices, and performs a signal detection using turbo equalization, and the device includes a transmission method determination unit 211 which selects a communication parameter of which a convergence property of turbo equalization is higher than that of a communication parameter which is used in a transmission method in which a spectrum is not overlapped with respect to at least one wireless terminal device, in case of performing data transmission using a transmission method in which at least a part of the spectrum is overlapped between the wireless terminal devices, and a control information transmission unit 217 which informs the wireless terminal device of the selected communication parameter. | ||
