Abstract
A communication device comprising: a wireless communication section configured to wirelessly receive a signal from another communication device; and a control section configured to estimate a reception time of the second signal based on the expanded signal matrix that minimizes the predetermined norm, wherein the control section executes the iterative calculation separately at a plurality of stages, sets a value of the regularization parameter used for the iterative calculation at or after a second stage of the plurality of stages to a value of the regularization parameter or more used for the iterative calculation at a previous stage, and changes the value of the regularization parameter based on a reception status of the second signal during the iterative calculation at or after the second stage.
