Comments and Corrections to “New Results on the Fluctuating Two-Ray Model With Arbitrary Fading Parameters and Its Applications”

In “New Results on the Fluctuating Two-Ray Model With Arbitrary Fading Parameters and Its Applications,” by Zhang et al., closed-form expressions were proposed for the distribution of the received signal-to-noise ratio in the fluctuating two-ray fading model with arbitrary fading parameters for millimetre wave bands. This correspondence provides some comments and corrections to the published closed-form expressions along with several novel analytical results.
