Not really. The fundamental problem is still there where the attenuation is high at certain frequencies in C/Ku/Ka. The way they mitigate it is to use different modulations and code rates in each frame so you don't need to bring the quality of the entire link down due to one user. However, the tradeoff is that the system capacity goes down fairly sharply as a result of this.
