Abstract
There is provided a communication apparatus capable of effectively removing interference waves from a received signal while reducing the computation load. The communication apparatus includes a weight calculating unit. The weight calculating unit includes a calculating unit and a selecting unit. The calculating unit calculates a first weight and a second weight. The first weight is obtained, for a target known signal being an update target, by updating, using the target known signal, a weight of a first another known signal updated immediately before performing an update using the target known signal. The second weight is obtained, for a target known signal being an update target, by updating, using the target known signal, a weight of a second another known signal. The selecting unit selects one of the first weight and the second weight that has a lower estimation error.
