Receiving device, receiving method, and receiving program

Abstract

To provide a receiving device, a receiving method, and a receiving program, which are capable of reducing performance degradation in a case where the spatial correlation of a channel becomes high. A transmission signal candidate search unit searches for a transmission signal in a direction in which reception performance is degraded, in MIMO signal detection. A transmission signal candidate generation unit generates transmission signal candidates while suppressing degradation due to the spatial correlation of a channel. In a decision unit, using the transmission signal candidates generated in the transmission signal candidate generation unit, a maximum likelihood sequence is obtained. The maximum likelihood sequence is obtained as transmission signal candidates where a metric is calculated and the metric becomes a minimum.
