In this paper, the optimal modified performance of the single-input multiple-output (SIMO) linear time-invariant (LTI) systems is investigated. The performance bound is related to the scaled factor, the inner factor of the plant and the spectral density of the reference signal. The output dimension also plays an important role. The strong restrictions of the directions for the reference signal and the assumption that the plant must have an integrator in the existing conclusions are not necessary. Also the modified performance index overcomes the invalidity when the state error is not zero vectors.
