Correction to "Optimally Joint Subcarrier Matching and Power Allocation in OFDM Multihop System"

In the above paper [1], the author gives that is always greater than 0 as in [1]. However, should be

(1)

where . It is observed that the denominators of (1) and in [1] 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 [1] cannot be obtained. Meanwhile, the extended proposition in [1, Section ] does not stand.
