Abstract
A method of determining a filter of a relay and the relay for performing the same are disclosed. The method of determining a filter of a relay to minimize data estimation error in a relay environment considering a direct link includes (a) setting a power constraint condition of the relay so that maximum value of eigenvalue of a transmission covariance matrix of the relay is less than maximum transmission power usable at respective antenna; and (b) determining a transmission filter of the relay using the maximum transmission power usable at respective antenna according to the set power constraint condition.
