where . It is observed that the denominators of (1) and in  are the same and positive whereas the numerators are different. From (1), it cannot be assured that is always greater than for example, when , . Therefore, the total channel capacity is not always monotonically increasing function of for the given power allocation, and and in  cannot be obtained. Meanwhile, the extended proposition in [1, Section ] does not stand.
