Enhancing Spectral and Energy Efficiencies in a Cognitive Radio CRAN with PUEAs

Algorithm 2

RPF MAOMP.

1. Establish network topology (RRHs and their respective users).

2. Obtain channel values and calculate the rate per RRH.

3. Predict the next channel state of RRH users using RPF algorithm.

4. Apply MAOMP (in Algorithm 1).

5. Drop detected PUEAs in 4.

6. Calculate the rate based on legitimate users.

7. Evaluate SE and EE based on equations (29) and (30).
