| 1. A method of transmitting/receiving signals in a mobile communication system, the method comprising the steps of:
i) calculating in a first receiver a reception weight value for creating a reception beam of the first receiver based on a
reception signal and calculating in the first receiver a transmission weight value for creating a transmission beam of a first
transmitter of a counter part based on the reception weight value;
ii) creating in the first receiver feedback information including the transmission weight value; and
iii) transmitting in a second transmitter the feedback information to a second receiver of the counter part,
wherein the reception weight value is calculated based on the reception signal and an output signal created by applying the
reception beam to the reception signal, by using one of a Constant Modulus (CM) scheme and a Decision-Directed (DD) scheme.
