<p>Provided is a communication apparatus capable of effectively removing interference waves from received signals, while reducing the calculation load. A base station apparatus (BS2) comprises a weight calculating unit (8) for calculating the weights of received signals. The weight calculating unit (8) comprises a calculating unit (8a) and a selecting unit (8b). The calculating unit (8a) calculates first and second weights. The first weight can be obtained by using a target known signal, which is to be updated, to update, for the target known signal, the weight of a first other known signal that was updated just before such updating using the target known signal. The second weight can be obtained by using a target known signal, which is to be updated, to update, for the target known signal, the weight of a second other known signal that is different from the first other known signal. For each of a plurality of received reference signals, the selecting unit (8b) selects, as the weight of the received reference signal, a weight, the estimated error of which is smaller, out of the first and second weights.</p> |
