PROBLEM TO BE SOLVED: To provide a receiver and a radio apparatus for which the influence of nonlinearity is reduced. SOLUTION: An RF part 12 receives packet signals in each of a plurality of antennas 10, and a storage part 28 stores reference signals for at least a part of the received packet signals. In this case, the storage part 28 stores two or more kinds of reference signals for which the degree of nonlinear distortion is different. A subtraction part 30 and a weight calculation part 32 derive a weight vector on the basis of the stored reference signals and at least a part of the received packet signals. Also, the subtraction part 30 and the weight calculation part 32 derive the weight vector for each of the two or more kinds of reference signals. A selection part 18 selects the weight vector of a small error in derivation among the two or more kinds of weight vectors, and a multiplication part 24 and an addition part 26 executes array composition to the received packet signals by the derived weight vector.
