| 1. A method of generating a reception beam weight for generating a reception beam from a reception signal, the method comprising
the steps of:
determining a first error value by using a first scheme at a timing point, and a second error value by using a second scheme
different from the first scheme at the timing point;
determining a first scheme application weight and a second scheme application weight, each determined differently based on
the first error value and the second error value;
generating a third error value using a scheme that combines the first scheme to which the first scheme application weight
is applied and the second scheme to which the second scheme application weight is applied; and
determining by a weight calculator a reception beam weight using the reception signal, the third error value, and an output
signal generated by applying the reception beam to the reception signal, wherein the reception beam weight is used for generating
the reception beam,
wherein the first scheme application weight and the second scheme application weight are determined using a sigmoid function.
