The unicasting relay protocols in multi-input-multi-output multi-relay systems are analyzed. The expression of the received signal-to-noise ratio with unicasting relay protocols is derived,which is a function of some singular values and angles between singular vectors related to backward and forward channels. Based on the maximizing capacity criterion,the relay selection strategies with instantaneous and average channel state information are presented with simplifying the capacity expression. With average channel state information it is a trade-off scheme between the feedback overhead and the ergodic capacity performance.
